I bought a lot of them on glass-shop.com some months ago. They are really great and not as thin as other glasses. However I am not so sure about the lid. I bough silicon lids like these, because I wanted a quick possibility to open them, but they suck. They are not tight at all, it’s more like you lay them on the glass. I want those to be tight and safe against food moths. What do you think about the traditional lids like depicted in your photo? Are there better ones, that make it more comfortable to open the glasses?
