What you are purchasing here are 45 by 52mm (Layflat Dimensions) tamper seal shrink bands. These work best for Hot Sauce Bottles, Tubes and Other Narrow Containers. Directions: Place shrink band around the lid of the bottle that you will be shrinking it to. Apply heat with the use of a heat gun or heat tunnel. I dont recommend using a blow dryer; its possible but not worth it unless youre only doing a small quantity of bottles. The shrink bands are easy to heat and durable. Have any questions at all about the shrink bands? Just send me a message and Ill get back to you as soon as I can!
