Micorsoft Surface Pro 3 pen clip with usb holder

Push fit pen holder for Microsoft surface pro 3. Pushes over your surface pro and keyboard to hold it closed. Pen pushes in and clips into the top. Has a spot for a small USB device (I use it for a wireless mouse usb receiver.

All the push fits are nice and tight so I haven't had any issues with things falling off after a few weeks of usage.
