The 38 mm X 26 mm clear shrink bands can fit a large variety of products and are great for 1 oz and 2 oz glass round bottles. These shrink bands provide security and safety for products with a tamper-evident heat seal and their durable 2 mil thick PVC plastic material. These clear shrink bands add this protection without creating a large headache with the removal process through a single vertical perforation and can be paired with our heat gun kit for an effortless application as well.
