From bubble tea to oolong milk foam, Taiwan has nurtured a one-of-a-kind hand-shaken drink culture, turning “reusable cups and eco-friendly bags” from simple tools into a statement of attitude. Bone’s “Eco-friendly Cup Tie” was born in this urban rhythm of life—making sustainability not just a responsibility but an easy, stylish, and worthy choice to carry every day.
At 3 p.m., a familiar hand-shaken drink is an irreplaceable ritual for many people in Taiwan.
From bubble tea to oolong milk foam, Taiwan has nurtured a one-of-a-kind hand-shaken drink culture, turning “reusable cups and eco-friendly bags” from simple tools into a statement of attitude. Bone’s “Eco-friendly Cup Tie” was born in this urban rhythm of life—making sustainability not just a responsibility but an easy, stylish, and worthy choice to carry every day.

You’re Not Unwilling to Be Eco-friendly, You Just Lack an Easy Reason
Many people have bought drink carriers, but fewer than 30% are willing to take them out daily. The reason is simple—too heavy, hard to hold, or hard to match. Sometimes the handle is too short, sometimes the bag is too soft, and sometimes it’s simply forgotten and buried deep in the bag. Bone observed this usage dilemma and proposed a simple yet clever solution: “Why not let your reusable cup wear a stylish outfit?” The Eco-friendly Cup Tie is not just a functional design but also a style statement. Bone’s exclusive interchangeable “Dodo Button” system allows users to switch characters freely according to their mood, outfit, or holiday theme—from classic Bone characters like Maru the Penguin, Patty Duck, Mr. Moose, and Meow Cat to licensed Pokémon series. Each button is like a tiny badge of daily life, telling today’s story through your Cup Tie.

This Is More Than a Strap—it’s a Portable Extension of Your Lifestyle
The Cup Tie body is made of eco-friendly silicone material—waterproof, stain-resistant, and washable. When dirty, simply rinse under the tap. Its elastic stretch design automatically adjusts to fit different cup shapes, whether it’s a large, chubby drink cup or a slender coffee cup. It holds securely and is easy to carry, truly achieving “good-looking and practical.” Walking into your neighborhood drink shop, as you hand over your reusable cup, the clerk glances at the cute button on your Cup Tie and casually asks, “That’s adorable, where did you get it?” You leave with your freshly filled hand-shaken drink—without a plastic bag, gaining an extra sense of ease and goodwill—making eco-friendliness the most natural part of daily life.

Design Rooted in Life ── Securing Not Just Your Cup but Your Care for Daily Living
You can hang it on the side of your backpack or carry it directly. Unlike traditional carriers, the Cup Tie design frees your hands, allowing you to move freely—whether commuting by scooter or strolling in the park on a lazy afternoon. More importantly, the silicone material Bone chose is not just an “eco-friendly” option but also a promise of durability. This is not just a short-term response to a plastic reduction policy but a daily essential that can stay with you for a long time.
Cup Tie 2 ── The Next Evolution of Eco-friendly Style
After the first-generation Cup Tie received user love and feedback, Bone launched the upgraded Cup Tie 2
, enhancing the outdoor experience for hand-shaken drink lovers and coffee fans. Cup Tie 2 maintains its sleek, minimalist design while optimizing comfort in every detail.
Retractable strap design: The strap can be secured back onto the Cup Tie for storage, making it neater when placed on a table or while drinking.
Slip on in one second, automatic tightening: No knots, no slipping—intuitive to use and ready right out of the drink shop.
Lightweight and space-saving: Easy to store and fold quickly, it fits neatly into your bag without taking up space.
These are not just upgrades but a reflection of “user-centric thinking”—allowing the Eco-friendly Cup Tie to extend from style to practicality and comfort.
Sustainability Starts with “Wanting to Use”
Bone doesn’t need to preach “you must go green”—instead, it uses a simple Cup Tie to invite you to rethink every small choice in daily life. You might not remember to bring a reusable cup every day, but if you get into the habit of carrying this Cup Tie, it will quietly remind you: “This is great already, and doing a little more is even better.” Rather than chasing perfection, start with a Cup Tie—tie up a bit of your lifestyle and loosen the distance to sustainability.
