I almost thought you were talking about the plastic, but now I realize you're probably talking about stickers.
They match, so... yeah.
Also thanks for the info Rox - I had assumed that vinyl sticker material was easy to find since replacement stickers are readily available. (Is this why the DaYan Gems don't come with 14 colors?)
And I know I could just replace the stickers or buy unstickered puzzles, but it's really hard for me to apply them because my hands shake too much.
