Shrink Wrap Bags purchased for a project, only used a few so there are approx. 90 pieces remaining in this package. 13 7/8” wide X 20” long – can be cut to fit items of different sizes. Clear PVC Heat Shrink Wrap used for multiple applications: packaging gift basket, shoes, jars, homemade DIY projects and more! You just put the item in the shrink bags and then use a heat gun, heat tunnel or hair dryer to shrink and seal bags evenly until it is surrounded completely. PS: hair dryer is the last choice for its less perfect shrinkage rate.
