The IsoMeaure dispenses one capful of Isotonix® product with one easy turn. We recommend using one IsoMeasure with each bottle of product, keeping it tightly attached to the bottle with the valve closed when not in use. It can be disassembled into 3 parts for easy cleaning. The IsoMeasure makes a great gift to your new customers by giving them the tool to make their experience with your Isotonix® products simple and spill free. This product is important for building the brand but more importantly it provides easier use of the product and helps your business grow. Remember these promotional items pay for themselves in many ways, build your business fast!
