12 PCS Hat Size Reducers, Hat Inserts to Make Smaller, Felt Cap Size Reducer Tape Black and White Hat Sizing Tape Hat Size Reducer for Hats Caps Sweatband

Easy to use and works well.

I like the fact my hat now fits, the inserts were a little thick so I only used one. Very pleased with the result.

Did the job.

Used these hat reducers on a trilby and made it fit me in seconds,no hassle

The sizes are too far apart so either have to buy too small or too big

Perfect for the job

Good Hat Sizers, but a little too thick.

Great little purchase
