Clear, rigid display tube designed for merchandising bulk buttons in a compact, orderly way. The cylindrical body nests tightly in trays or on shelves to maximize space and keep colours and sizes easy to view. A smooth twist‑off lid opens quickly yet holds securely to prevent spills during handling or customer browsing. Ideal for studios, classrooms, and retail counters, the tube keeps small notions together, reduces clutter, and protects contents from dust. Affix a sample button to the cap so shoppers can match at a glance; lightweight and reusable for long‑term organization.
