For any pawpad orders, you have the option to give them a special "coating" of sorts. This must be made aware of when the pawpads are being ordered, of course. The pawpad shown above demonstrates the various effects that they could include.

Finger 1: Small red glitter
Finger 2: Blue shimmer powder
Finger 3: Gold powder
Finger 4: Large silver glitter
Palm: Silver shimmer powder
Finger 5: Red shimmer powder

I also have a variety of other colored glitters that can be used in place of these, those were just showing the difference between small glitter and big glitter. I also have colored bar glitter and other colors of shimmer powder. So really, almost any effect can be given! They're really neat and add a bit of zing to your pawpads. :3
