DENTEN Calculator Numeric Keypad 2in1 Bluetooth Wireless Mechanical Switch Type-C Charging (Brown Switch) It can be used as a calculator and a numeric keypad with one device. Keycaps and key switches are customizable. This product is fun with its clicking typing sound. I mainly use a laptop, so I bought this thinking a numeric keypad would be convenient, but I've gotten used to entering numbers on my laptop and only used it once, so I'm selling it. Outer box included, and all accessories are present. Since this is also listed on other sites, please comment before purchasing. Thank you.
