Nuphy's wireless keyboard features a stylish and colorful key layout. Purchased from the Nuphy official website and used stationary on my desk. It's a low-profile mechanical keyboard. I've tried various keyboards, but this one feels exceptionally good to me, in terms of key feel and sound. It has brown switches. The US layout has a more beautiful design, but I'm reluctantly selling this one because I'm switching to the JIS layout. Originally, it had white keycaps, but I also purchased gray genuine keycaps and swapped them, using them in combination. Of course, the white set is also included. I will also include the original case, so those who want to carry it around can use it with peace of mind. I'm sorry, but I've thrown away the outer box and stickers, so please be aware of that. I think it's a beautiful item with little use; the mirror-finish part on the back of the main unit still has the protective seal on it. - Model: Air75 - Color scheme: Gray, Yellow, Orange, Green - Key layout: US layout Thank you for your consideration.
