Is the HHKB stickers the exact size as the official decal? And is the sticker easy to put on? Looks like each letter is separate and I'm now that good at aligning stickers.
Stickers are made from measurements from the original, I would say really close to the original.......
They are easy to put on. Peel and paste, there's 2 layers like a screen protector. Peel bottom and paste on surface, leave it to cure for around 12-24 hours, remove top layer.
It should stay on for an extremely long time.
