AKIRO Film Canisters with Caps 35 mm Empty Camera Reel Storage Containers Case Plastic Storage 15 Pack Transparent

I am an elementary science teacher and bought these canisters for Alka-Seltzer Rockets. They work perfectly for this, as the lids fit tightly and allow the pressure to build up and create high flying rockets (they will bounce off ceiling). The tight fit can be a downside if you are trying to have 2nd graders and below use them, as some may not have the strength to open the canisters themselves. I love bringing the experiment to any class as it is always a fan favorite, and these canisters are partially responsible for how cool the experiment is.

I purchased these to put in my diabetic emergency pouch. They hold a weeks supply of lancets, a couple pen needles and keep everything tidy! Its a bit “outside the box” use but its great!

These work great for fishing hooks

All canisters worked well. Some canisters started to leak after 3 - 5 uses. Overall worked well and good value.

These are great for dice, chips and just organizing small materials for a classroom! Great value to the money
