[Wurkin Stiffs] マグネットカラーステイ 磁気カラーキーパー 2サイズセット 2ペア トラベルセット ケース付き プラスチック メンズ ホワイト

中に磁石を埋め込むために、ステイ自体に厚みがあります（1㎜よりやや厚い程度）。 そのためす襟ウラのステイ挿入袋（？）に入らないことも多いです（合わないものもけっこう多いです）。

My husband loves these - has been using Workin Stiffs for years!

These are amazing. I had purchased a few brooks brothers shirts that didn’t lay right on my shoulders. Really thought I was going to have to get rid of them it was so bad and brooks brothers is not cheap. These keep the collars in place look much nicer now. Awesome product very strong magnets

Works like a charm. Wow, the magnets are super strong!

Excelente producto, los imanes son potentes y deja firme el cuello, los materiales son de buena calidad, muy contento con la compra

I really like these. They keep your collar in place all day. I’ve had my set for two years, and I don’t use them too often (I have a lot of button downs and shirts where the stay is sewn in) and I’ve only used the 2.5” set. Yesterday when I was separating them (the magnets are quite strong), one of the magnets embedded in the stay ripped out. Then the one in the other stay came out also. Not sure what happened. I’ll use the 2” ones for now and see if they work in my longer collars. Overall, though, these are a great men’s accessory. (Regarding what I said about the magnets being strong, where they are in the picture is as close as I could place them and keep them separated. So yeah, these will hold things in place.)
