Selected User Reviews For 20mm 13mm Vial Rubber Stopper Set, 100 Count Mushroom Shape Self Healing Injection Ports, Safe Bottle Stoppers for 13 mm 7 mm Opening Glass Vial and Liquid Culture Jars (50 Pcs 20mm, 50 Pcs 13mm)

This is not a very durable material

3/5

The holes left by needle injections are too large for most people to deal with. Although these appear to self-seal, I am not sure that they really do. In the past, I have bought bigger red ones that have worked great countless times and do not look like there is a hole left after use. You should not use these if you're growing mushrooms. These are not worth the money, there are better options out there. The life of these small things is very short, so they aren't worth it, poor quality.
