I bought a pack of these to use as a sample for my work shirts. My goal was to replace the collars on all my shirts, but they didn't quite meet the requirements. First, the price for a pack of 10 collars (worth 5 shirts) was a bit high (I'm expecting $5.99 or maybe $6.99). But I'm willing to pay if it means I don't have to deal with corsets that don't hold up (especially in the wash). Unfortunately, they did not meet this requirement either. I've had them for about two and a half months and two out of ten have fallen out and I couldn't find them. Overall they are of decent quality and they met my needs until a few of them fell off. Outside. I have about 12 work shirts, so I'm not going to spend another $20 to accessorize the rest of my shirt with corsets that won't hold up. You may have luckier luck than me, but for $9, you won't. - Follow me.
