All stackable - yes, that's it - unfortunately delicate glass

Addendum - 2 stars
Well, the joy of the beautiful container, the first rinsing not survived untarnished. On average vessel a piece of glass is broken off from the edge. Fortunately there was no injury on the hand by the splintered piece.
The packaging imprint "Made of robust borosilicate glass" looks a little like a mockery.

Shipping a bit longer than with Amazon Prime lasted - but Amazon itself would only be able to in a couple of weeks ever deliver - but delivery time was within the estimated delivery time.

The containers make a good impression, they are due to the glass thickness reasonably hard (that's probably important when it comes to use in the microwave) and act dibasic. What indeed was not as described, but actually what I had somehow expected, in view of the dimensions of the individual containers that they are space-saving stackable together with the lid. It works like this but only with the small, the purely fits in the middle container (so they are also delivered).

Let's hope they prove themselves long in use. If my wife is in the kitchen, it clatters sometimes quite like - hopefully glass jar are robust enough ...
