Wee Blue Coo A3 Black Wooden Picture Frame 11.7 x 16.5 Inch (29.7 x 42cm) Acrylic Safety 'Glass' Photo Frame

What can fit in this frame? Description says 11.7 x 16, but title says 11.7 x 16.5.

Could we remove the protective glass if we wanted? Say if we had a scratch off map that we would need to have easy access to the map itself?

Is the frame matted

What sort of UV protection does this material offer?
