30 Pack Bottle Pourers Dust Covers Anti-Drop Rubber Dust Caps Pour Spout Sealed Cap for Stainless Steel Classic Tapered Pourer Stopper Vinegar Olive Oil Bottles

They’re rubber, so they’re pretty much universal for a variety of pourer sizes. I bought a couple of oil vinegar bottles that didn’t have stoppers on them. These fit perfectly.

I use these a lot of these for all of my bottles of oil, vinegar, etc. Gotta have a cap to keep the air out. These come in quite handy, work well, and I never have to worry about losing or breaking one by always having extras on hand for when the need arises.

These caps are a must have if you aren't using your liquor bottles for any length of time. Keep those fruit flies from ruining your booze without having to worry about losing the cap. I have used the other nipple caps that don't have the retainer and you might guess where those ended up. These are a good value for a 30 pack.

They do the job in covering... but they slide right off, especially when using oil, but still slides off with the vinegar too. Also, when you pour, the cap gets in the way... major mess, so you have to hold the cap to one side while pouring...

These little spout caps are very versatile. I make my own vinegar and add these caps to the spouts to help keep the vinegar from splashing out of the bottle when being transported. I also use on my olive oil dispensers. The spouts help minimize additional oxygen from getting into the bottles. Oxygen, over time, will give oil a rancid quality. These caps just give a finished feel to the package. They are flexible and the keeper ring that fits over the spout helps keep the cap in a close location. I've lost a number of caps that did not have a keeper.Very handy and highly recommend.

Simple item that performs as expected. I have these pour spouts on some olive oil and liquor bottles and I wanted to keep them sealed up better and these caps worked perfectly.
