I was building a Tofu65 and needed 3 more months for my GB. I grabbed these since I had no little shifts lying around, and they work. They only come in 65% layout, but in this situation, they were good. They were thin, but durable.
This set gives you exactly what the photo shows, and no more. But if you have a keyboard with that layout that needs keycaps then these are great. They also mix nicely with other similarly coloured and sized keycaps.
