I absolutely adore the milk glass look of these. I also adore that it comes with a lid! my only issue is with the lid itself..it doesn't seem to seal at all whenever put in place. I've tried several ways of getting the lid flush/secure to no avail..so, for stacking I can see this being an amazing product..but for using the lid to seal and store food, I'm not sure if I'd trust it to seal or not. still a beautiful design and lightweight!
