Shrink Bands for 2 oz. Roll on Bottles. Dimensions: lay flat 64 mm x 105 mm. In addition to their low cost, a tamper-evident shrink band can provide the look and feel of a quality packaging seal without interfering with its appearance. To ensure a correct fit, measure the widest diameter of the cap and container. The minimum and maximum size is listed above. These are specially made for us and are guaranteed to fit our (and others’) 2 oz. roll-on bottles.
