HEAT RESISTANT GLASS VACUUM STORAGE CONTAINER1040ML RECTANGULAR

After using it a couple of times, a thin crack appeared in the lid. Maybe I used the pump to make it airtight that was sold separately to remove too much air. If possible, I would like to see a lid sold separately.

After using it three times, a crack appeared in the lid. The other parts are working fine, so it seems that there are some that are good and some that are not. If the quality is good, I would like them to make other sizes too.

I was looking for a container to make nukazuke in the refrigerator. Until now, I've been using plastic containers, but this one is made of glass, and the size is perfect. Because it's glass, the nukazuke stuck to the rim can be easily wiped off with a kitchen towel.

At the moment, there are only three sizes, but I would like them to make more sizes. I think that the freshness is maintained by vacuuming. Before use, the lid is wrapped in something like cling film, but it was difficult to remove.

I think there is a problem with the way the lid is fastened. Is it because I'm not very good at it? The white seal doesn't stay in place and comes off easily, and the plastic that supports the seal on the lid breaks, so I bought three, but two of them don't stay closed. I'd like to buy just the lids, but I'd like you to sell them.
