They are thinner also, and look MUCH better on your Valk. The only problem is that have to cut them all out, and that takes a while, especially if you have lots of Valks to sticker.. But the result in the end is worth it IMO. And to get the stock Yamato ones to look somewhat acceptible, you need to cut off all that hideous flashing anyway. So, spend the time and effort on something that will look better.
Oh and if you are reading this Takatoys, any chance of a 001 Max "Fast Pack" Sticker sometime in the future? I would love my Max 1S to have fast packs. I know it was never seen in that way in the movie, but it still would be cool to have.
Thanks
