Now, here's a Numberling stamper. I made the transparent shape by ripping it from some PDFs. it was tricky, but I was able to manage accquiring the shape. I added a transparent texture to it so that it can stand out against the background. Currently only supports Official Numberlings (0 - 40, alongside multiples of 10 up to 100.)
c2a Extra Numberlings for unsupported Numbers are included in a seperate sprite.
