They work great for holding eggs but the lid does not stay closed so I have to keep it closed with a rubber band. Also, there is no airflow so the eggs will start to grow mold after a couple weeks so I drilled holes in them and it seems to have worked. Personally I wouldn't buy them again or recommend them.
