Shot glass Tequila Skull Skull Skeleton Set of 2 I received these but I don't use them... I'm not sure if they're glass or plastic. Both have stains and black spots like in photos 6 and 7. I am a novice, so I may have overlooked something. Please check the condition in the photos. The following are important notes: These items will be shipped from a remote island, so it will take some time to arrive! In past transactions, it has taken about 10 days for delivery after shipping. That's why I've priced them cheaply. If you are concerned, please purchase from someone else. If you are in a hurry, I'm sorry, but please refrain from purchasing ( ; _ ; ) To prevent any problems later, such as "It's too slow!", please only purchase if you understand this.
