Hi sgt_pepper! Welcome!
The decalgirl skins cover nicely but do leave an edge (no pun intended

) showing all around. I would think it would look cool having a red rim around the black and white composition skin, but if you think not you might want to get a skin with red in it. Don't forget you can make a skin from any of their artwork, which is fun!
Hope you and your friend enjoy your PEs!
