This is enough keycaps to fit a Planck Keyboard (a 40% keyboard containing 48 grid keys, or 46 + 1 double width key. Note that this doesn't contain that double key.)
This has also been updated: The previous version had printing problems with the sprues. They've now been bulked up to 2mm, which means they will be harder to cut. I have not tested these with wire cutters, but they should be fine to cut (as long as you order plastic - I cannot guarantee metal).
The keycaps themselves - I received them unpolished. The nubs just need a little bit of filing down (removing the fuzzy plastic printing powder) before they were able to fit - it's a very tight fit. If you file them down more you can control how tight the fit is.
Note: There may be discoloration issues with some of the keycaps. I've adjusted the margins between the keycaps so there should be less discoloration, but there still could be some.
