The quality of this product was mediocre ( the products were made of cheap non-durable material). Given the price, I should have expected this, so I am not necessarily saying it's the seller's fault. It was just disappointing that the shot glass slightly cracked given how tightly it was screwed onto the shaker. If you're looking for a cheap cocktail set for one party, this is great. If you're looking for something more long-term I suggest you invest a bit more.
