PeneTrex Caps 38mm - Package of 3

If you are tired of making a mess and wasting oral liquids, replace your original screw-on caps with PeneTrex Caps. The patented Seal-Tex membrane allows liquid to be withdrawn from a container using either a regular luer tip syringe or a needle without unscrewing the cap. When the syringe or needle is removed, the Seal-Tex membrane completely reseals itself and is good for multiple penetrations. Available in 2 handy sizes.
