Reusable Portable Cup
Pocket Tumbler is an innovative reusable tumbler developed under the philosophy that “small choices create big changes.” Designed for both modern convenience and environmental responsibility, it redefines what a portable cup can be by combining hygiene, mobility, and sustainability into one patented product (Korean Patent No. 10-267549).
Unlike conventional tumblers, this model features a unique double-structured, collapsible design that enhances both functionality and portability. The inner cup, made of high-quality platinum silicone, can be completely turned inside out for easy cleaning, ensuring maximum hygiene.
The outer cup is crafted from durable ABS material, providing stable support and long-term structural integrity. This combination offers a seamless blend of safety, cleanliness, and resilience, tailored to fit the needs of active, eco-conscious consumers.
A sliding height adjustment mechanism allows users to adapt the tumbler’s size according to the amount of liquid or the situation, making it ideal for travel, work, or outdoor activities. Weighing only 250 grams, its lightweight and slim design enhance portability and make it easy to store in small bags or pockets.
Furthermore, its heat-resistant silicone construction allows safe use in boiling water, microwaves, and even ovens, without any deformation or material degradation, even after repeated use.
Beyond practicality, Pocket Tumbler embodies the vision of a zero-waste lifestyle. By encouraging the use of reusable products, it promotes sustainability and helps reduce disposable cup waste.
The product represents a perfect harmony between minimalistic design and eco-friendly innovation, offering consumers an elegant yet responsible choice for their daily routines. With this model, the message “Small choices, more meaning” comes to life—demonstrating that every individual decision contributes to a more sustainable planet.
