Citrus Circles are deodorizing wafers for the diaper pail and give off a nice clean citrus scent. They are made of the same blotter paper as deo disks with a oil based citrus scent applied.  They are nontoxic but of course they should not be ingested. They are individually wrapped and are made in the USA.   They fit in the slot of the lid in the 54 quart diaper pail and also in the netted pocket that you can add to our pail liners.
