I think these are a really cool idea, you get the awesomeness of a sticker, but not the bumpiness you can sometimes get from having a sticker on a surface you ride over and such. AND, they're in the shield logo design, which is an amazing logo imo, so, yea, I really want to try some of these!
I know they're not the first to offer vinyl stickers, but, yea, its something new from flatface and you can also buy them individually.
More designs coming soon also! I think its a much better way for stickers to be done in fingerboarding, as its such a small scale thing that even a 0.5mm bump of a sticker on the ground can be noticed, and these should be a lot better for that :)
