I buy these mugs often, - These are the mugs to buy! I don't say that lightly, I have purchased other sublimation mugs from other vendors and they have come broken and cracked and damaged boxes. Cricut has sturdy boxes with three boxes inside the thick outer box. It keeps the mugs secure as they are all in their own box. They these are the 15 oz mugs. There is 36 mugs in this set. There are different  size mugs and different count size boxes. Each mug has the Cricut logo on the bottom of each mug. I recommend these mugs to anyone who loves to make mugs!
