The manufacturer provides the following information: With the help of this set, it is possible to mod mechanical keyboards with Gateron, Kailh or Cherry MX switches. The set contains a total of 105 keycaps, which are suitable for keyboards in the 104-key ANSI-US/QWERTY layout. Glorious PC Gaming Race also includes an additional ASCEND key that can replace the ESC key.

Unfortunately, our suppliers no longer offer the requested item.

The keys are basically compatible with Gateron, Kailh or Cherry MX switches. This means that if Razer has not chosen a different size of "cross" for their own Green Switches, it should fit. I had a quick look on YouTube. I found a video in the search bar : razer blackwidow elite with glorious key caps enter

There are only black ones, but you can also get them at digitec Glorious PC Gaming Race ABS Keycaps (CH, ISO, 105 keys)
