## Description

desertcart.com: Outus 23 Pieces Hat Size Tape Reducer Hat Sizer Insert Foam Reducing Tape Roll self Adhesive(White+Black) : Industrial & Scientific

Review: Work great - Received the tape rolls and they were easy to apply. I was not sure if they would work, however I placed them on easily and they stuck on well. The tape cannot be seen since they are placed on the inside and quality is very good. These tapes have allowed me to wear several of my hats. With these tapes, my hats don’t move around and fit very good on my head now.
Review: Simple Fix That Works Perfectly for a halloween mask - Picked up this Outus tape to use in a Spider man mask that was a little to loose — and honestly, this kit works great. The foam strips are super easy to use: just peel and stick inside the hat band, and you’re done. Also didn't have anything rubbing off on my face even after a few hours of wearing the mask. I like that it comes with a bunch of pieces (23 total) in different sizes, so you can adjust however much you need. The material feels soft but sturdy, so it doesn’t make the hat uncomfortable or mess with the fit. You can even double them up if the hat’s really loose. While I used it for another fuction that it was meant for, it worked perfectly. Easy, comfortable, and does exactly what it’s supposed to.

### ⭐⭐⭐⭐ Hat fits finally!
*by P***A on June 6, 2025*

This product does its job. Some complain its not sticky enough. I found when installing it, you should press it in place and keep pressing for a bit and it stays. I received a cowboy style hat and a baseball cap for birthday gifts and both were too big. Now they git nice. I would buy again.
