Used to safely apply heat shrink capsules, also called thermoscapsules, onto wine bottles using a 110v electric element. Place your heat shink on the bottle and completely push down. Slide the bottle up the channel until the bottle hits the end. Immediately remove bottle. Very fast and a safer hands off approach than using hot water or a hand held shrink gun. Completely made of stainless steel which is very nice for longevity. Stainless won't rust with repeated use and is easy to clean, ensuring that your label does not get dirty while apply heat shrink.
