Collar Expander

Do you have a shirt or two that fits everywhere but the collar? We do too, but we don't like leaving the top button completely open so enter the inexpensive, but effective collar expander! 

Use collar expanders by wrapping the flexible spring around existing collar button and collar to increase size by up to 1/2". Expander stays hidden as it loosens tight collars. They are reusable, rustproof and slip on and off. 12 per package.


  • Loosens tight collars
  • Increases collar size by up to 1/2"
  • Stays hidden
  • Metal with nylon stretch guard inside stainless steel loop
