SKS offers the 40 mm X 45 mm clear shrink bands that are 2 mil thick here in a bulk option. These shrink bands are made for smaller bottles such as 7 cc natural round bottles or 2 oz glass bottles with fine mist sprayers and create a tamper evident seal for added safety and protection for the products. These shrink bands do not create a large obstacle when opening the product due to a single vertical perforation that makes removal easy and our heat gun kit we offer can save a lot of time when applying.
