[Unanswered]  What type/material of decal does the BB-10 use/what size? (Pegasis Decal)

I got an Aquario decal ready to print out so I can use it as a custom decal to stick under my stadium - I just need the dimensions (inches) and what kind of decal I need in order for it to stick under! If you know, it would be helpful. Thanks so much!

Here's the decal I'm gonna print out!
