little bag of silicone heat bag

New kind of heat bag, little bag of silicone inside, remove the bag of silicone from the beautiful Pouch outside. Heat Silicone for 1 minute only. Can also use AS A COLD BAG. I was given this, because I already have my wheat bags, I gave it to a friend. Cost about NZ$20. This one looks very cute, and 1 minute is fast. But inconvenience of removing the outside pouch. I prefer my old fashion ugly looking self made wheat bag.
