At Ultimate Fusion we are continually trying to improve our products to benefit you the Customer. In keeping with this philosophy, we have made changes to our product bottles. We have incorporated new flip top lids that have a leak proof seal inside, this can be removed for use. The bottles are very slightly larger to better accommodate 15ml products i.e. mediums. Based on feedback we received, we feel these are a better option to our previous lids, as these on occasion, could be troublesome. The new bottles will be 'phased' in, so orders may be made up of new type and old type for a short transition period.
