This is a hard-to-find Pampers promotional gift - a travel wipes carrying case.  It has a wrist strap and velcro closure.   This is for the MINI or TRAVEL size wipes packages, not the regular sized wipes packages.

BRAND NEW, multiple available.

The length is about 7.5" (so assume it should fit a wipes package that's about 7.25" in length) and about 4.5" high (so it will fit a wipes package about 4.25" high).
