The sponge counting bag is formed of front and back sheets of transparent polymer material which are joined at the edges and bottom to form an open-topped bag. The back sheet extends above the front sheet. The front sheet is folded down to form a cuff, and the lower edge of the cuff is stretched to form wrinkles whereby the lower edge hangs outwardly away from the bag so that the cuff can be manipulated easily to pull the bag open. In one species, the top of the back sheet forms a flap which can be folded down to cover the otherwise open top. This flap is detachably, adhesively attached so that the bag normally remains closed, but can be reopened if necessary. Another species has a plurality of cuffed bags arranged one above the other so that the plurality can be hung from one support.
