bar@drinkstuff Liquid Activated Flashing Shot Glasses 2.1oz / 60ml - Pack of 6 - Light Up Shot Glasses

fun, not sophisticated. The first one we took out didn't work at first

2 out of the 6 shot glasses didn’t work. Bought to give as ‘university settling in gift’ . Sadly items were not in my possession when realised faulty. As they were in uni halls. Found amazon and company very unhelpful in situation.

Only 3 worked and 1 wouldn’t stop till battery died.Complete waste of money
