HR® Lubricating Jelly 1.25 oz. OneShot® is a sterile single use alternative to our 2 oz. Flip Top Tube. Research has shown that a 2 oz. tube is too much volume for many procedures, so we have developed the 1.25 oz. package to cut back on waste. The OneShot® is designed to significantly reduce the risk of cross contamination.HR PHARMA
