Shrink Wrap Slider.

I make both melt and pour and cold process soaps. I find it very frustrating when I'm trying to wrap my melt and pour soaps and the soap gets stuck in the plastic bag. This alleviates a lot of the problem. I slide the bag over the top and then slide the soap in. See how it works below. You can enlarge the item for bigger/wider soaps.
