This set contains a wallnut in 4 different angles in transparent PNG format. They’re raw and have no layer styles applied to them (e.g. shadows). The high-quality images can be used for whatever you consider fit.
You are under no circumstances allowed to redistribute or sell these resources as your own. I give everyone full permission to use them in both commercial and non-profit work, without asking anything in return.
It would be nice if I could see how and where you used them and I encourage you to leave me a link with your finished work and/or link back to my website from the place you posted the original work, however, this is not mandatory, it is just appreciated and I would consider it a sign of common courtesy.
