The basics The tapered tip syringe is made to carefully transfer precise amounts of material into small openings. The benefits The syringes do not leak and the plungers glide smoothly to prevent accidental discharge. The uses Use them to precisely transfer fluids from large to small containers, even those with narrow openings, and quickly measure paints for mixtures without losing material. Artists even use Jacquard syringes to apply mediums, such as resists, paints and dyes, directly to fabric, canvas and paper. the specs Material: PolypropyleneColor: Clear (natural)Capacity: 10 cc (10ml) OuterDiameter: 0.71"/18.03 mmInner Diameter: 0.63"/16.00 mmDetails: Industrial Grade Safe, Silicone FreeThe ends are molded tapered tips with an approx. 0.003"/0.8 mm ID hole The bottom line The syringes are easy to clean, because paint and other liquids do not stick well to the polypropylene plastic or the easily removable rubber plunger.
