This 3″ wide EasyFit Syringe Cover is especially made to fit coiled tubing. Simply “drop” your 3 way syinge into the top and it will land in the correct position for immediate use. No need to look for the opening or to manually feed the syringe tip through. The tapered design reduces the volume of material under your thumb allowing for better tactile control. This cover also works well with most of your handpieces.
