Occasionally I will find a new, unopened Nipro 3ml syringe in my box that looks a bit damp where the plunger meets the injection end of the syringe. I just found one that appears to have a small amount of thick, clear liquid/gel that you can see stitching from the plunger to the syringe when pulling back the plunger. Has anyone else experienced this? Doesn't seem normal? Anyone have any thoughts?
