Clear Perforated Shrink Bands for Hot Sauce Bottles and Woozy Bottles [1" - 1 1/8" Diameter] (250 Pack)

It works great as soon as you figured out how far you should push the sleeve onto the part you want to shrink wrap, in my case very small bottle necks to seal the cap. It needed a few trials with hight setting and heat setting from your heat gun. In my case a very small heat gun with 2 settings approx. 7" long used to heat shrink sleeves on electrical parts works fine for those shrink foils. My heat gun uses only 350W on highest setting and I use only the lowest setting.

They are easy to use and shrink on exactly how I want them to.

Easy to use.Will buy again.

not what I expected
