These die-cut labels fit perfectly on the bottom of you Glock magazines and make it super easy to identify your magazines. A sheet of 24 decals will allow you to label lost of magazines, and still have some left-over. They wear fairly well, but will get dinged-up over time if you drop your magazines on the ground in competition. But that's why there are extras. :)
Order different colors for different calibers, or different capacities, etc.
These decals are cut to fit Glock OEM 9mm and .40 cal magazine base plates.
