I bought one set for my brothers birthday and liked them so much I bought a set for my roommate birthday and myself! these are a life saver with all the diff stupid sizes they have now for mens dress shirt collars and then you accidently wash the collar stay that came with the shirt and its ruined because its flimsy material. These are the perfect price, super smooth, no defcts I can detect and I have been able to fit them on all my work shirts from Bannana, J Crew, Gap, Calvin Klien,... They are absolutly one of the best purchases I have made on amazone and would recomand them to any and every male I know who wears a modern dress shirt.
