LUXEAVANT INNOVATIONSLUXEAVANT INNOVATIONS Slick Collar Adjustable Shirt Collar Support System Bundle Set with Collar Stays and EDC Storage Metal Box, Men

Can be used on any shirt or polo shirt. Props up the collar well.

Although I did have second thoughts on buying this as I felt it was expensive for 2 pieces of plastic. But considering I've had to struggle with my collars got them anyways. As mentioned, it stays as a proper collar support and does its job. Adjustable on hob big your neck is. I would recommend this.
