Iwaki 日本 Psc-Prn-G7 耐熱玻璃儲存容器綠色 7 件裝系列

These nest very well so you only need the footprint of the largest item to store them all. The clear lid and sides make it easy to see what is in the container. I had to get used to how to remove the lid, but once I did, I appreciated how well the lids fit. I haven’t checked if it is leak proof though.
