it is clear DM isn't it? and no - you cannot add anything to it
I don't mind you DMing it for protection - just nothing that changes the raw look significantly and definitely no colouring
OH yes it's definitely clear and hiding in a box but I also have an accents one that is clear but gives a crackled look though it doesn't change the raw look - mmmm I have something already one with it so will hunt it out and if I can get to my printer and get it out of the box and assembled we might just get to put up a pic for you to look at.
I won't colour or bead or glitter - DM just gives me that 'want to add to it' feeling a lot, that's all rofl.
