Soft and cute
Color: White Ice Set, Color: White Ice Set
I love the size, I have a 75% keyboard so I knew size wouldn’t be an issue. I love the color it matches my keyboard perfectly! It feels nice to rest my wrists on but I haven’t used it consistently just yet so I’ll update this if anything changes but it feels soft and nice. It’s thick and doesn’t sink in when pressure is applied. All round it’s great thus far!
