Small Universal Stopper - Solid

You suck. Don't give false descriptions of your products to mislead customers then tell them its their issue that the item number doesn't match the description.

Great fit and tight seal

I purchased these stoppers for the 3 gallon carboys and they work great. I’m using them to collect Hydrosol (distillate) from the essential oil making process and they work perfectly. If you’re using them for a similar purpose just make sure there is a dry surface on the bottle and the stopper, even a drop of oil will break the seal. When used dry these stoppers are a great fit and have a tight seal. P.S. Their customer service is stellar in my experience!

Plugs a Hole

Yup. These stoppers do a good job of plugging up my carboys and keeping air from getting in. They’re made of a tough, flexible plastic that will give you years upon years of service.
