Where do I find the expiration date on my bear spray canister?
This is a very common question and a very good one. If you turn the canister so you are looking at the back, there is a diagram of proper usage and the expiration date is stamped perpendicular to the diagram.
The product should be used or disposed of at the end of the year stamped on the canister as the performance of the product is diminished after that date.
Storage and disposal information are also located on the canister.
