pros: This product is very helpful for a novice going into learning how to tattoo. while it isn't completely skin like, it gives you a pretty good idea about how hard to push in and how much ink you should have on your needle. cons: the ink doesn't wipe away very well, so if you're planning on using one of these to showcase or frame your pretty much S.O.L. it tends to look pretty messy by the end of it. But again, great for practicing.
