Compact closed-lid brewing, focused on aroma and flavour
The Rock 'n' Dew SE Core Set brings the essential closed-lid brewing system into a more compact 6 cm short-handle format, designed for easy storage, stable handling and expressive coffee service.
Developed from DragonFly’s research into aroma-focused coffee service, Rock 'n' Dew uses a sealed brewing approach and sculpted glass geometry to help retain volatile aromas, guide liquid movement and present coffee with greater clarity and depth.

SE Core Set – Short Handle Edition
This version uses a compact 6 cm handle to reduce the overall footprint while maintaining a secure grip and thermal separation from the hot glass body. It is especially suited to smaller brew bars, shelves and coffee stations where space matters.
Closed-Lid Brewing for Aroma Retention
Brewing with the lid in place helps reduce aroma loss during extraction. When the lid is opened for serving, retained aromatic compounds are released toward the nose, helping different fragrance layers present more clearly during tasting.
Water-Wave Interior Geometry
The server body features a wave-like spiral texture inspired by moving water. Brewed coffee follows the sculpted glass surface as it enters the vessel, encouraging controlled circulation rather than a direct drop to the base.

Designed for Gentle Swirling
The reinforced base and handle allow the server to be swirled gently after brewing. This movement helps mix the coffee evenly and release aromatic compounds without aggressive stirring.

High-Borosilicate Glass Construction
The server is made from food-contact high-borosilicate glass with a food-contact silicone sealing ring. The glass components are heat resistant up to 150°C.
What is included
- Rock 'n' Dew transparent glass server body

Bringing Contemporary Chinese Design into Filter Coffee Brewing
Founded in 1996, DragonFly Design Centre 清庭設計 is a design-led brand built around the vision of founder and creative director Jeff Dayu Shi (石大宇). Rooted in contemporary design inspired by Chinese culture, the brand has developed a distinctive language that brings together craftsmanship, symbolism, and practical innovation across lifestyle and coffee objects alike.

Inspired by Culture, Designed for Brewing
For DragonFly, coffee equipment is more than a brewing tool — it is a meeting point of culture, form, and sensory experience. Their filter coffee designs often draw from traditional Chinese visual references while translating them into modern brewing objects with strong functionality. The result is a collection of drippers and servers that feel both expressive and purposeful, made for brewers who value character as much as cup quality.

Precision in Filter Coffee Design
DragonFly’s coffee line is especially known for its thoughtfully engineered manual brewing drippers. The CT62 Coffee Dripper, designed by Jeff Dayu Shi together with Jake Yuan Cheng Hu of Taster’s Coffee, features a 62-degree cone angle, a structured groove system, and a design intended to promote more stable flow, reduce clogging, and support even extraction. It uses standard V60 01/02 filter papers, making it approachable for both professionals and home brewers

Where Aesthetics Meet Performance
What makes DragonFly stand out is the way it approaches coffee equipment as both a functional brewer and a design object. The surfaces, textures, and structural details are not merely decorative; they are integrated into how the brewer manages water flow and extraction. This balance of beauty and brewing performance gives DragonFly a unique place in the specialty coffee world, especially for those drawn to original drippers with a strong identity.
Recognised in the Coffee and Design World
DragonFly’s brewing designs have gained international attention not only for their visual language, but also for their technical thoughtfulness. The CT62 has been described as a dripper that combines cultural inspiration with functional brewing design, and DragonFly’s newer coffee pieces — including the rock ’n’ dew coffee server and Tri-Spin dripper series — were recognised by the German Design Award 2026 for their combination of aroma-focused design, extraction control, and user experience.
A Distinct Voice in Specialty Filter Coffee
From drippers to servers, DragonFly Design Center brings a different perspective to specialty coffee: one that is deeply design-conscious, culturally rooted, and focused on elevating the ritual of hand brewing. Their coffee equipment speaks to brewers who appreciate not only clarity and control in the cup, but also the meaning and beauty of the tools they use every day.

Condition of Returned Products
You may inspect a product to the extent reasonably necessary to establish its nature, characteristics and functioning, similar to what would normally be possible in a physical shop.
Please return the product complete, including its accessories and, wherever reasonably possible, its original packaging.
If a product has been handled or used beyond what is reasonably necessary to inspect it and this results in a reduction in value, we may deduct the corresponding diminished value from the refund.
Refunds During the 14-Day Withdrawal Period
For a valid withdrawal of the complete order, we will refund:
- the purchase price of the returned products; and
- the cost of our least expensive standard delivery option originally available for the order.
Additional delivery charges resulting from choosing a more expensive delivery method, such as express shipping, are not refundable.
If only part of an order is returned, the original delivery charge is not refunded.
The direct cost of returning the order to Kohiraifu is the responsibility of the customer unless the product is faulty, damaged, incorrect, or we have agreed otherwise.
Refunds will be made using the original payment method. We may withhold the refund until we have received the returned goods or until you provide evidence that the goods have been sent back, whichever occurs first.
Voluntary Returns – Up to 30 Days
In addition to your statutory rights, Kohiraifu may accept eligible products for return for up to 30 days after delivery.
Returns requested after the statutory 14-day withdrawal period are part of our voluntary return policy and require prior approval.
For returns between day 15 and day 30:
- The product must be unused, complete and in resalable condition, preferably with its original packaging.
- The customer is responsible for the return shipping costs.
- Original shipping charges are not refundable.
We reserve the right to decline voluntary returns that do not meet these conditions.
This voluntary return policy does not limit any statutory consumer rights.
Coffee, Matcha, Food & Consumable Products
Certain statutory exceptions to the right of withdrawal may apply to products that deteriorate or expire rapidly, or to sealed products that are not suitable for return for health or hygiene reasons once their seal has been broken.
Opened coffee, matcha, food products and other consumable products cannot be accepted under our voluntary return policy once opened or used.
This does not affect your rights if the product supplied is faulty, damaged, incorrect or otherwise does not conform to your order.

Please keep the product and its original packaging until we have reviewed the case.
Where the product is confirmed to be faulty, damaged or incorrectly supplied, Kohiraifu will arrange an appropriate solution and cover reasonable return shipping costs where a return is required.
Your statutory warranty and conformity rights are not affected by this policy.
Exchanges
If you would like a different product, colour or variation, please contact us first.
Depending on the product and stock availability, we may arrange an exchange or ask you to return the original product and place a new order.
Wholesale & Business Orders
The statutory consumer cooling-off period does not apply to purchases made for business or professional purposes.
Wholesale and other B2B returns are therefore subject to separate conditions and require prior written approval from Kohiraifu.
This does not affect claims relating to products that were damaged, faulty or incorrectly supplied.
