Apparently this is not a palm-sized mini keyboard, but no doubt, the mini bluetooth keyboard with silicone cover is more friendly to use.
This wireless keyboard measures 283 x 123 x 25mm and weights 390g. As we can see from the images, it features modern, elegant design. On its compact QWERTY layout, there are 80 low-profile, responsible keys to provide you a comfortable typing experience. Apart from that, the Bluetooth keyboard is powered by 2 AAA batteries, so you will never worry the built-in rechargeable battery is failure. The assorted keyboard cover can also protect the mini keyboard from dust.
The mini Bluetooth keyboard with silicone cover is available in two colors, including black, and white. Each one is priced at $35 USD. If you’re interested, jump to USBGeek for more details.
