It doesn't stick, but it's not very reusable either.
1. The silicone o-ring is trapped in the plastic. It cannot be washed properly. It would be nice if the plastic top of the plunger came off. A screw type cap maybe?<br />2. The writing comes off easily. It needs a protective coat. My solution at the moment is to cover the markings with packing tape.<br />3. The seal can get slightly loose at times, as though it should be the tiniest fraction wider. Not loose enough to start dumping the contents everywhere, but enough so that it loses a millilitre or so when trying to fill it sometimes. Some of the syringes in the pack are a little more prone to this than others.
