FusionsThe Worlds Best Hat Size REDUCERS in Felt (& adjustable) Easy FIX & Long Lasting in Black, Black, 4 x 6 x 1/8

I've ordered 4-5 different kinds for my brimmed hats and I just never liked them. The other spacers would be way too think, and even be rubbery.These new spacers have the perfect amount of thickness. They seem to be a strong material that is still breathable. They are sticky enough to not move, but not so sticky that you can't pull them off to shift them around, if you need to.

I bought 2 new thats from Nick Fouguet and I love them both but they came just slightly large so I bought this product and I have to say it was made my Nick hats so comfortable that they feel like they were a bespoke design so I am so so happy!I would say buy this product without hesitation!

These self adhesive felt hat sizers are perfect for The job. They were easy to trim and stayed where I put them. It has been months since I put them in my hat and they’re still doing their job.

Good back up if neede

These work fine, but don't stick very well, at least not at first. I stuck them on again and they seem to be holding so far.
