These work really well for sealing up the caulk tube between jobs. Plus they are colorful!

Actually works
Would RecommendFinally something that actually fits and keeps caulk tubes from drying out. I've tried duct tape and tube plugs from Temu, but this product is superior. For the cost of one tube of caulk, you can save 5 for future use

They actually work!!
Would RecommendAwesome product!! I’ve tried screws, electrical tape, wax paper. I put one of these on a tube of calk and over a month later it was like I just opened the tube!! I bought another pack on my next trip to Lowe’s.

Wrap it up
For years, I have tried many different ways to plug my caulking tube. Most of them 100% did not work a couple of them semi worked, but had their downsides. I knew there had to be a better way and thankfully I found it. You most definitely should buy these if you are like me. A simple DIYer who never uses an entire tube at one time if you always have some left plug it up with one of these. It protects your money and your time. I promise you you won’t regret the purchase.

Great caulking tube saver.
Would RecommendI just had a few inches of caulking to place, and was worried I would waste a whole tube. Then I noticed these sealing caps. They have great grip and totally saved the tube for several weeks.

DOES THE JOB!
Would RecommendI have bought some of these before and they do work. Helps to keep the unused caulk from drying out too quick. I used to wrap painter tape or duct tape around the opening of the caulk to help to keep it from drying out but these work much better.
