Happy to hear it sounds like you'll all be getting ISO orders soon.
I bought these keycaps for my GMMK TKL and they are amazing value for money
https://www.overclockers.co.uk/cors...-black-uk-layout-ch-9911060-uk-kb-0b3-cs.html Great keycaps. Better than Razers, Corsair took the time to finish their mould properly, so no rough edges and the inside second layer covers the full keycap. Better shine-through consistency as well.
Just a shame with the Pro being a non-standard bottom row, keycaps like the above
won't work. Obviously you can use them, but it's then finding some keycaps from another set for the small modifiers.
I really hope Glorious do a Pro TKL model to refresh the GMMK TKL. I've gone from a Hades 69 to this and I have to say I think TKL is my sweetspot. Makes keycap hunting for UK ISO a bit easier/cheaper and still saves some desk space over full size.
The world of ANSI is much kinder for keycaps than ISO, let alone trying to get proper ISO UK.
