HEAT RESISTANT GLASS VACUUM STORAGE CONTAINER 370ML RECTANGULAR

The vacuum packs I used before were either made of stainless steel or plastic. The stainless steel ones couldn't be used in the microwave, and the plastic ones would absorb smells and colors depending on how they were heated, which was stressful to keep using. This product is made of glass, so it solves all of those problems at once. It's a little bulky because it's made of glass, but I'm still satisfied with it. There are various sizes, so I'm considering whether to get a bigger one next time or to get more of the same size.

I bought two of each the 370ml and 650ml sizes, but within a month the transparent protrusion on the 650ml lid that snaps shut was broken off. The 370ml is fine for now. I think the smaller size is less likely to be damaged, so I recommend the smaller size over the larger size. Please sell the lids separately.

The first time I used it, I was able to store it in a vacuum. After the second time, there was a problem with the lid, and it didn't become a vacuum. The lid breaks in various places very quickly. The lid develops cracks. The lid fasteners break. The packing doesn't fit properly. I can't recommend it.

I like the glass. The handle on the lid comes off easily, which is a problem. You need to know how to close it properly. I'm going to buy a few more because they're good value for money and easy to buy. It would be great if you could sell vacuum-packed bags as well, please.

I've only been using it for a week, but I'm finding it very useful because it's cheaper than other brands and easy to use. However, I'm a little doubtful about whether it maintains a vacuum state or not, because I'm not sure how I should be using it. After I'd let the air out, I was relieved to find that the lid wouldn't open because it was in a vacuum state, but the next day the lid opened easily. I think that vegetables keep well in this container, but the meat has discolored, so maybe it's not sealing properly. I think it would be better to wrap the food in plastic wrap first and then put it in this container. If anyone knows how to do this, please let me know.
