This package makes it extremely easy to inject spores into jars without infecting the burnt needles prior to injection. I also tend to get clogged needles so when I got a bad clog, I just swapped out to a fresh needle.

A great price for the absolute basics. Not much else to say about this.

Awesome that I can buy a few extra needles and not 100! I always seem to char mine to a crisp after injecting a bunch of jars.
