OFFCUP Plastic Test Tubes, 40 Pack, 16 x 150mm with Cork Stoppers

The clear plastic tubes let you see what is inside at a glance, which is useful for presenting sweets, bath salts or small craft items. Cork stoppers and a small funnel are included for filling and finishing the set.

Each tube measures 16 x 150mm. The pack also contains round kraft paper and rope, so it can be used for decorated party favours as well as straightforward storage.

The tubes are plastic rather than glass. That makes them lighter and less prone to breaking than glass tubes, but they are not the right pick if your project specifically calls for glass.

Key points

The set contains 40 transparent plastic tubes with cork stoppers, along with 40 round kraft paper pieces, 2 ropes measuring 10m each and a small funnel. This gives you materials for preparing several matching gifts or decorations without sourcing every finishing item separately.

The clear sides make the contents visible, which can help when using different colours or fillings for a display. The corks are designed to fit snugly and can be removed for access. The product information says a tightly fitted stopper helps keep air and liquid out, for liquids, make sure the cork is seated firmly rather than assuming the tubes are suitable for every storage situation.

Fit and sizing

At 16 x 150mm, these are slim tubes for small portions, samples or decorative arrangements, not general-purpose bottles for larger items. Their narrow format suits sweets, seeds, powders, jewellery and bath salts when the contents fit comfortably through the opening. The included funnel may make filling easier, particularly with smaller loose contents.

The stated size is the tube size, not a listed capacity, so there is no volume figure to use when planning liquid storage. If exact dimensions matter for a display or craft project, note that the product details mention possible measurement variation from manual measuring.

Practical tips

For party favours, fill each tube with a suitable small item, close it with the cork and use the kraft paper and rope as part of the presentation. They can also be arranged as simple decorative pieces or used to organise small craft materials. Because they are transparent, labels, ribbons or marker decoration can help distinguish contents, these decorating materials are not included in the listed pack.

The tubes are described as easy to clean and reusable. Handle the corks separately while washing, and allow the tubes to dry before refilling. It makes sense if you want a coordinated set for DIY projects, small gifts or visible storage, depending on how you use it. If your priority is a glass vessel or a stated capacity for measuring liquids, this pack does not provide those details.

Before you decide

What comes in the pack? It includes 40 plastic tubes and 40 cork stoppers, plus 40 round kraft paper pieces, 2 ropes measuring 10m each and a small funnel.

Can the tubes be reused? They are described as washable and reusable, making them suitable for repeated craft or storage use when cleaned and dried between uses.

Are they suitable for liquids? The product information says a tightly fitted cork helps prevent leakage. That claim depends on the stopper being firmly seated, so avoid treating them as guaranteed leakproof containers.

Buying verdict

Choose this set when you need multiple slim, clear containers and want corks and basic presentation accessories included. It is a practical alternative to assembling tubes, stoppers and decoration materials separately, especially for party favours or small DIY displays. Not the best choice if your project requires glass, a specified liquid capacity or a container size larger than 16 x 150mm.
