As a lover of Men's Fashion, i highly recommend these Solid Brass Collar Stays. Based on our own experience, they elevate any dress shirt with a touch of sophistication. The sturdy brass material ensures that your collar won`t wilt or fray unlike flimsy plastic stays .However, the assorted sizes can make it difficult to find the right size for your collar, but overall, these are a must-have addition to any man's accessory collection..
