description fits it.... sort of.

they are the proper dimensions. but they are not the proper weight or balance of live cartridges. i have had problems with them flipping and/or actually flipping out of my lever action rifle. they are made of a weak metal, it appears to be aluminum, that is already getting chewed up. the actual "snap" part of the snap cap is not actually a spring to buffer the firing pin, just a small rubber insert that i am not confident will hold up to repeated abuse.

these will probably work if you are just training a single new shooter and then tossing em, but if you are like me, and constantly teaching people, with 100's of rounds of chamber, fire, and eject drills, you will need something more durable.
