This is a Sure Fresh brand set of 10 small mini plastic storage container set - great for craft items, food storage, or any small items.  They have white plastic lids and are available in a rectangular shape.  They are 2 1/4” by 1 3/4” and 1 1/2” tall. They are rigid plastic and the lids seem to fit really well.  Check my listings for the same 10 piece set in a round shape and different brand smaller ones in a 6 or 8 piece set.

Please check my other listings for a wide variety of products  - new and preowned.
