I bought two sets. They were exactly what I envisioned: They fit into the fridge door;  have thick and durable glass; have a secure top. During this time of COVID-19, it's not always easy to get to the store, so I buy an extra carton of milk.Pouring fresh milk into one, I freeze the rest in the remaining three pitchers. Truly, this is one of the finest kitchen products I've ever bought.
