This is a vintage container for Polident tablets, used for cleaning dental appliances. It is constructed from a light green plastic with a textured, ribbed design and a dark green screw-top lid. The manufacturer's logo and "POLIDENT TABLETS" are embossed on the front, along with a "Contains 15 tablets" label... Funny thing is half of the tablets are still in the vial!!  Cool collectible. Have a blessed day!
