Why choose KeepCup?

Considered design

In 2009, we designed the world's first barista standard cup.
As an effort to reduce single-use coffee cup waste, our cup would be the first to prioritise usability for baristas while offering a delightful drinking experience.

Since then, our commitment to innovation has never wavered. With our expanded range of modular bottles, cold cups, and camper cups, KeepCup continues to lead the charge in promoting reuse. Loved by companies, sports teams, and as campaign gifts, our services are embraced by partners worldwide, making a significant impact in pushing sustainability forward.

Make it your own

KeepCup offers plenty of vibrant colours and contemporary designs, providing endless options to craft the perfect graduation gift for your teacher or cherished sports team memorabilia. From customising down to the silicone band, our cups invite excitement as you bring your unique creation to the office for your morning coffee!

Made to last

Designed to be loved and looked after for a lifetime, the KeepCup is crafted from high-quality, durable materials with minimal environmental impact. Our entire range is modular, allowing for part swapping and easy replacement when necessary. Furthermore, all our raw materials undergo independent lab testing and are certified free of BPA, BPS, and BPF.

Join a community of reusers

KeepCup is now available in over 75 countries with our users diverting billions of non-recyclable, single-use cups from landfill and counting!

As an official distributor of KeepCup in Japan; Less Plastic and KeepCup are working together to find ways we as a community can enact change and better our environment through reuse.

1. Custom KeepCup

Let's make a cup that you'll want to use forever!

For many of our customers, using a KeepCup has been the beginning of their journey towards an eco-friendly lifestyle. Crafting a personalised branded KeepCup serves as an excellent avenue for promoting your brand and showcasing your company's commitment to forward-thinking values. Here are some customisation options:

↑ Cork Engraving

Engrave your design onto our 100% recycled cork bands. The appeal of cork is its thermal insulation and comfort for holding while drinking. This is our most popular customisation option as cork engraving is unique and brings a sophisticated natural look to your branding.

↑ Custom Colour

All KeepCup products are customisable across our range allowing for infinite colour combinations. Mix and match the colour of individual parts to better represent your brand. This service is complimentary for all orders exceeding 10 KeepCups!

Laser Etching

Our Thermal range is designed for lasting drinking pleasure and is a luxurious option for branded merchandise. Custom laser etching scratches away the exterior coating revealing your design in stainless steel. This is a sleek customisation option that works for both detailed and block designs.

↑ Steel Printing

Showcase your brand on luxurious stainless steel in full colour. Utilising Pantone colours, this service allows you to perfectly capture your brand identity with precision.

Silicone Print/Deboss

Silicone band printing and debossing allows for a wider range of colour options. Print in full colour using the Pantone colour system or minimal black and white. Debossing refers to when a design is imprinted into the silicone band, creating a depressed effect. The deboss technique showcases your brand with understated sleekness.

↑ Glass / Plastic Printing

Display your design on our glass range and durable plastic models. Choose this service to present your design creatively, with the option of using multiple Pantone colours for a vibrant look or keeping it sleek and minimal in black or white.
