This is a 13” power depth tom. It‘s 13” deep. It’s a composite drum that is either fiberglass or carbon fiber. It seems a bit thick for carbon fiber but is black inside (which is usually an indicator of a carbon fiber shell). It’s a small amount of thickness difference. The shell is about 3/16 of an inch thick. Both types make for excellent sounding drums. A 13” RIMS isolation mount is included. There are two extra holes in the drum where the mount must have attached directly to the drum. I received it this way. So you have a choice of using the RIMS hoop or mounting the bracket directly to the shell. There are some light scuffs but these drums are durable and the scuffs can be polished out. I will let you do that! The chrome could use some cleaning as well. Otherwise the drum is in very good shape.
