Black Film Canisters: 12 Pack. SUPER VALUE! 100% SATISFACTION GUARANTEE. New top quality professional product at a great price. These original containers come with better securely fitting lids because they seal from the inside, not the outside. Because the caps seal from the inside of the container this makes it less likely that the lid will catch onto something and be pulled off or detached from the canister. This provides you with a big advantage over regular black canisters if you are conducting activities such as geocaching and will be out in the field where 'snagging' the lid on something is more likely. PREMIUM PLASTIC CANISTERS are popular for their use as containers for science or lab experiments, kids school projects, or even salt and pepper shakers. GREAT for keeping supplies separated, or of course, camera and photo items. Sturdy and reliable; these canisters have endless uses. Get them now while they are in stock! NOT RECOMMENDED FOR MODEL or CANISTER ROCKETS. BUY NOW and SAVE!
