The product is very low quality. A lot of the lids break off just after a few times closing and opening. I found it odd that they all came open, but when I started closing them I understood why - thats because some of them break just when you bend the lid for the first time. Some are sort of fine, but most break very easily. I will not buy this item again and do not recommend buying it if you need the lid attached to the jar. Once the lid is broken off, it still seals the container fine, however you have odd parts where it used to join sticking out so it works, but it is obvious it is broken once you look at it.
goods well packed, arrived quickly. Quality is good as expected.
