These cufflinks are the epitome of men's fashion sophistication .The Swarovski crystals add a touch of glamour to any formal outfit, and the rectangular shape gives them a unique edge. Through trial and error, I found that they sit securely on the cuff, but can be easily removed when needed. The only con is that they are quite expensive, but they are definitely worth the investment for anyone who wants to upgrade their wardrobe with a touch of luxury..
