I’ve used these jars for years and never had an issue of any kind.

I've been buying from Midwest for years. Best prices you can find, well made products and consistency are why I've stuck with them.

Stelrile as hell and consistant

Came quickly and was exactly as I expected. Inoculated all 12 and no contamination so I’m happy.

I had originally ordered a kit from "North Spore" and they took so long I had to cancel the item. They didn't even keep in touch to say it's taking longer than expected. But midwest communicated every step of the way and even picked up the phone when I called to a question.

Also- The kit was very good, well made, and package securely.

As my needs arise I will order from them again.
