Keep your collar points firm & straight. Restora plastic collar stays are a great replacement for those collar stays that don't make it back from the laundry room or the dry cleaners. Restora collar stays are likely thicker and more rigid than the plastic collar stays that came with your dress shirt. Always remove collar stays before washing your shirt or leaving it at the cleaners. The shirt stays left in your shirt while ironing could melt and leave your collar deformed.
