The quality is fantastic, and harkens back to the days of zoot suits and pin up art. The way it is applied is very professional. The colors are great with full saturation. So if you're looking for a little mod to the appearance of your guitar or guitar case, I can highly recommend the Jockomo Wolf Sticker. I am currently looking at a few others for some of my other guitars. As for Cons: I really can't say anything bad about them yet. They claim easy to remove, and leaves no residue. I'm sure at some point we'll put that to the test, and perhaps then I would need to update this review. But I can say this, I am not the kind of person that puts decals on my guitars. In fact I don't use decals for anything other than the required certification labels required by the EU on my custom builds. That is it. But, this looked like an interesting option for the new Gibson 2019 Double cut junior I just bought. I like it alot!
