Review: Great, affordable little airlock kit - Great little kit for brewing. I was worried about the silicone bugs vs rubber but it turns out they're actually really nice, without the rubber scent that come with the rubber bungs. I use these quite a bit and love em. Great price for this little kit. I'm really glad they added the little rubber pieces to place into drilled out lids and caps to add airlock to containers that weren't meant to be used as fermenter.
Review: Fits 1 gal jug - These fit great in a 1 gallon wine jug.

These fit great in a 1 gallon wine jug.

### ⭐⭐⭐⭐⭐ Wine stoppers.
*by M***G on September 24, 2025*

I am new to wine making. The listing gives size by number. I need a larger bung, and it was not in the pkg. If the ad had shown size by a ruler or metric, I would not have ordered this pkg. However the product is top quality, and I will keep them to possibly use for other things.
