Keyguard for the Lenovo 300e Chromebook. Fits other Chromebooks that share the same keyboard. Note the drawing of the keyguard. If yours varies from the drawing on even a single key, the keyguard won't fit. Call for assistance if you can't tell.
Keyguards for keyboards and laptops default to 3/16" clear acrylic. 1/8" acrylic-styrene is available for users who require the openings to be shallower. It has a nice non-glare finish and a better warranty, but is more flexible and may become warped or dislodged.
No attachment method is provided with this keyguard. You'll need to attach it yourself with something like double-sided tape, Velcro, or mounting putty (Blu Tack, etc.)
