Box arrived sealed and every cartridge fits snug in my Byrna SD with no leaks when I pierced the seal. Fired off a full mag for practice and the pressure stayed consistent through the last shot. Glad I grabbed the 10-pack so I don't have to reorder every range day.

The ten-pack is a good value since each cylinder averages out cheaper than buying singles at the shop, and they fit my HD model without any hassle. I’ve fired off a dozen practice rounds and the pressure held steady until the very last blast.

These little cylinders slide into my SD model without any hassle and I’ve gone through about six of them during target practice. For the price, having a fresh cartridge ready for home defense beats carrying a half-used one around.
