This snack pack is 8″ tall and 5.5″ wide. It will fit a mini water bottle as well as a snack. The inside is wipe-able, and the whole thing is machine washable. With a Velcro closure, even your youngest of snackers can access this themselves. Personalize with any of the fun fabrics shown here ($10), or choose a solid color and get a personalized image (additional $3 per color). Another option is to have insulation sandwiched in between to help cold things stay cold, and warm things stay warm.
