Cup is beautiful although not glass. I bought 3 of these - two for Mother's Day gifts. Both recipients loved them although I had to advise them to put the mug on display in their china hutch and not use them for drinking. Why? Because a small heart was fused to the bottom of the cup on the inside and I was afraid of choking hazard. One recipient is 95 years old and that would definitely not be advisable of her to use for drinking. Thank you though - it is beautiful on display.
