If so, which magnets do you recommend?** A: I originally purchased the 1/4" diameter 1/16" thickness neomydium magnets based on someone else's recommendation. Although they did stick and hold, and were quite discrete at that size, they didn't stay on at all. I was literally losing them on daily basis because they would fall off just from the motion of me standing up from a seated position. I did try doubling up with two magnets per collar and the performance improved somewhat but was still disappointing. I decided to try larger magnets and ordered some 3/8" diameter neomydium ones with the same 1/16" thickness. That made all the difference in the world! They still are not bulky and noticeable inside the collar and now they stay on all day and usually even when I haphazardly undress in the evening and forget to take them off first, I find that they stick and are still there in the morning. Highly recommend the larger diameter. **Q: Will these stays work with the N48 neodymium magnets ? There is a mention in the description highlighting that the updated version does not !** A: While I don't know what the N48 is, the ones I purchased are Definitely attracted to my neodymium magnet! My stays are the 2 length 2.5 & 2.75, 18 each. **Q: how do I know how long my collar stay should be, is there somewhere on the shirt that tells me or should I just pull out a ruler and measure it?** A: A 2.5 inch collar stay is one of the most common sizes. These collar stays will fit in almost every shirt, and fill the area for the collar stays completely. You can always measure that little area with a ruler or get a package of multi sized stays but if you opt for the 2.5 inch package, they should work with all of your shirts. **Q: Do you Ship to Mexico?** A: Thank you for your question. Yes, we do ship internationally. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Wonderful *by D***G on 6 February 2026* Wonderful , so many more thzn you could ever need ### ⭐⭐⭐⭐ Good stiffeners but photos misleading *by D***I on 14 June 2024* The stiffeners are well made and do the job. Loses one star because the picture and description totally does not match what you get — 36 all the same size. I wish they were broader so they’d fit shirts better, but overall they work well. ### ⭐⭐⭐⭐⭐ Great value *by A***H on 4 August 2023* Useful to replace those flimsy plastic stiffeners. Just need to remember to remove them before washing your shirt, although I’ve left them in by mistake and as they don’t leave any marks (rust) there’s no issue in doing that. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/49604466-36-quality-stainless-steel-collar-stiffeners-in-box-2-5](https://www.desertcart.jp/products/49604466-36-quality-stainless-steel-collar-stiffeners-in-box-2-5) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-11*
