An insert lining for our Maxi Treat Pouch. This snug fitting lining is easily removed for washing, or to store in the refrigerator to keep food treats fresh. The Sock slides into the pouch and secures at the front and back to fit snugly, allowing one handed operation of the Maxi Pouch - no more cumbersome plastic bags to deal with. Treat Pouch Socks are made from a coated material to prevent food oils penetrating, so your Treat Pouch remains clean of food residue. A Sock also helps keep the pouch hinges clean and can prolong the life of the pouch. It is only available in black.
