Keyguard for the Dell Chromebook 3100 2-n-1 and the Dell 13" Chromebook 3380. It should also fit other Dell Chromebooks that use the same keyboard, but we have not tested them.
The default material is 3/16" clear acrylic. 1/8" high-impact PMMA is available for users who require the openings to be shallower, but is not recommended, since it is more flexible and may become warped or dislodged. There are also a number of 1/4" thick materials available.
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.)
