Design literally rubbed off in my nephews hands when only a few days old. Had many design pint glasses over the years - by far the most pathetic I've ever seen with respect to durability of the design. Essentially defective!
I'm disappointed that the color came off within two or three washings. If the engraving was slightly deeper, the design might hold up, but it's hard to see with no black on it.
This glass has d fashionable and amazing.
Love the idea and the glass is so unique!
