Cheap, easy and they work! Protects your caulk!

These actually do work great. I use a different one for every tube I open.

I wasn’t expecting much, but these little rubber caps work really well. I often tackle projects in stages, sometimes weeks apart, and I used to waste half-used $10 tubes of caulk because they’d dry out between uses. These caps have completely solved that problem.Even after several weeks sitting in my garage, the caulk inside stayed nearly as fresh as when I first opened it. No clogs, no dried tips — just pop the cap off and keep going. They fit snugly, are easy to use, and save both time and money. Highly recommended if you’re someone who works on home projects a little at a time.

Easy to put on, good idea for overnight or a few days but doesn't keep caulk / sika fresh for weeks, it will still clog up.

How did we not know these existed? These little things really help keep your caulk or construction adhesive from drying up and wasting your money on buying more. They are easy to apply and take off.

These thing are so quick and easy, and save me lots a money, making my caulk tubes last longer

These are a godsend to save expensive caulking. Wire nuts, screws, OEM caps - none of them worked to prevent a clog. These work great and don't fall off or rust. They also don't impact the hole you've cut in the tip of the nozzle. Such a great idea - I wish I would have invented them.

These caps claim to be reusable, but dry clogs can get stuck inside, making them impossible to clean. Soaking in the solvent is of no help. Prying out the residue will damage the cap. After being used twice, they are just clogged plastic waste.
