ZAKIRA Hat Size Reducer Foam Tape Roll - Self Adhesive Strip Insert 60cm (24in) Dark Grey

It was easy to and worked perfectly

Easy to fit. Would have liked the band to be thicker and take up more room. It is very difficult to find hats to fit a 54cm head as most are made to 57cm. This took up about 2cm of the gap. So better but not perfect.

Great have ordered twice both times stetsons.perfect as. I have small head

The strip works but after a while the adhesive gives up and you have to repeat the process. Best for an occasional wear not a regular wear

very easy to install. under the rim of the hat. Very good way to make the hat smaller.

it does the job very well

Use this for my rain hat.It's super!I have walked in the wind and the rain and everything has comfortably remained in place.I was most pleasantly surprised!

I was shocked to receive a tiny piece of thin cheap foam. I can’t believe the cost of it for what you get. It doesn’t even work. For that price you would expect a roll and even then it would be poor value. You might as well buy a piece of foam from a kids craft shop and cut a strip yourself for pennies. I’m so disappointed and angry at what I received. It’s a joke. There customer service is terrible too. I fed back how unhappy I was and they emailed back telling me I am wrong and offering me no solution to sort it out.
