35mm Film Canisters with Caps (35 Pack) Plastic White Empty Film Canister Case Bulk with Lids Storage Reel Containers for Storing Film, Small Accessories, Beads

Just what we needed for some of the science experiments we're doing in class this year.

Used them for Alka-Seltzer rockets with my home-schooled 11-year old. We had a hard time finding lids/canister combos that fit tight enough to build up pressure. And sometimes the lids were too difficult to snap on in time for liftoff. But when we found a winning combo, they flew so high we lost them in the sun. We had to hunt around our backyard to figure out where they had landed. I suppose it was a good lesson in patience and persistence, and we were able to finish some pages in my son’s science workbook.

Hard to find item. These are a bit difficult to open the first few times, but are good quality.

Product was immaculate and as expected.

The right size for me. Handy and priced right.

As advertised at a good price.

Can't go wrong with these. Bought them for my used film while on our trip through Asia and they worked as they should.

Just as advertised

Worked very well for the experiment that we had in mind

The good: - They are inexpensive - The container is made with strong plastic and is durable. - The lid holds firmly and is completely watertight. It will hold its content securely. The bad: - The lid's ribbed rim is too narrow and made to poor tolerances: it barely sticks out of the canister's exterior diameter and it is eccentric (sticks out more on one side than the other). - Since there's almost nothing to grip onto, the lid is very hard to pry open even if you have tough fingernails. - The plastic used to make these is too stiff and it's not translucent enough to see the contents of the bottle. Conclusion: It gets the job done but it leaves one longing for the original 35mm film bottles which had all of its qualities and NONE of its faults. I would prefer paying more and getting a better quality product. Overall I am disappointed and I will not be buying these in the future. In fact, if I find better quality ones, these ones are going to the recycling bin.

Way to hard to get open or closed I don't have finger nails really so getting it open is impossible
