I own other "Umbra" items and these seem counterfeit in comparison.  They're plastic and the "Umbra" symbol is literally a sticker that comes off and came attached crookedely.  Again if it wasn't advertised as Umbra I'd probably be happy with the price/product but really missed the mark in comparison to other products I've purchased under the same brand. 

Updating to further say how disappointing these were.  DO NOT BUY THESE KNOCK OFFS
