Each of the two blocks is protected by a thin plastic film cellophane type surfaces were so perfect when unpacking.
This Plexiglass is really very good and absolutely did not flinch when I drilled to attach an object of almost 2kg whose center of gravity was shifted enough. No stability problem either because it is massive.
This is the kind of support I love to put a value to an object, it is simply placed on it, or as in my case, screwed.
Very Satisfied!
