These always end up looking awesome. Flawless! Have used them on many different projects like placing my business logo on notebooks or folders, printed a few with my friend's coffee shop logo to customize boxes... possibilities are endless. Being able to find a template and customize it helps a big deal.
I normally print on the white matte sticker. For a specific project I needed a clear sticker and it did not disappoint. I use Avery labels since I can remember. Great quality as I am used to have with the signage/car wrapping vinyl films as well.
