A vinyl, weather resistant sticker! They are 3" at their widest side
Almost all the stickers have a white outline EXCEPT for:
> Yellow Spotted Turtle
> Japanese Word "Sakura"
> Spotted Turtle
> CCS feature
> CCS Terrarium
These have clear outline which really help accentuate the design. So while you see white in the image it is just the backing/ sticker paper that you peel off.
