Excellent jars for storing small amounts of spices, where they stay fresh for quite a while.
I have bought them before and they are very durable, maybe one broke because it bumped hard against another due to my poor storage.
They arrived very carefully packaged.
Note, the shiny caps shown in the 1st and 2nd images are plastic and painted silver, but there are also more matte ones (3rd image) that are metal type inox (I received both types, half and half). In the description, they are referred to as "metal cap" but this does not apply to all the products I received. The plastic caps retain odors, the metal ones do not.
