like it is an acrylic brick [SEP] this thing is heavy like it is an acrylic brick i have a glass vanity and so i am slightly concerned with the heft of this with that said it is an excellent product i would never ever use it as picture however even though it is quite weighted that just looks like a disaster waiting to happen your eyeshadow would shatter for certain with the weight of the organizer hitting it should it falli use mine like a drawer of sorts my glass vanity has a shelf and i put this on it and then pull it out when i need to select a palette it works great if the palettes are slim you can fit two to a row
