Once the 2 parts are completely mixed, you shove it in your ear. You keep foldins the edges in as it squishes out and around. Its not messy though. Anyways, you push in on it so it goes into the ear canal part way and after 10 minutes you can remove it and repeat the process on the other side. I formed a little area to grip them when I made these
Here is the finished pair. After forming they need to cure a few hours
These are the Most Comfortable hearing protection I have ever used. I made my first pair of these over 3 years ago and have used them every range trip. They block sound a lot better than the basic “Roll and insert” foam plugs. They hold up. I can still use my first set from over 3 years ago, but the were beginning to look grungy. My first pair was blue. Currently on Amazon I found red, orange and tan. Ear muff type protection could easily and comfortably be worn along with these.
If you have tried a variety of hearing protection but never quite found the just right type, I would suggest giving these a try. Like I said, I have used these for over 3 years and will never go back to conventional, one size fits all, earplugs. At less than $10 they are affordable enough to give a try. Did I say how comfortable these are???
