Young children have “sipper cups” to hold their grape juice. Now, it’s time for their moms to have their own adult “sipper cups”. With our “mama’s juice” wine tumblers moms can sip their favorite fermented grape juice without spilling any. These are 12oz stainless steel tumblers with a tumbler size of 4.7″ × 3.5″ and come in a variety of colors. Any of these tumblers would make for a perfect holiday gift.
