Both of my kids got one of these retro ice bags for Christmas from their Aunt Jill and we absolutely LOVE them. I love them so much that I thought it would be a great addition to Polkadaisies gifts. They can be used with ice or cold or hot water. So these aren't just great for kids, but adults as well. I will be using one the next time I get one of those horrible head aches. Cute gifts and especially great for Easter baskets! Price is $15 each.
