Wow, these things look awesome, I'm just about to apply them to my black competition pushbuttons. I actually got mine in the mail yesterday but it was so buried in the pile of junk mail I forgot about it.
Weeding with a pushpin is So simple btw, you can literally poke and lift the extra vinyl.
btw, when placing the 1up guy on competition pushbuttons, TRIPLE CHECK YOUR ACCURACY! I put my 1up guy way on the right, and the 2up guys slightly towards the right. I was fine with the 2up guy but I had to peel off the 1up guy and try another one, this time overcorrecting to the left which made it align perfectly.
-thanks a bunch Nannuu, these things are pretty awesome *as long as no one picks at em*
