They also lose their shape quickly and can become deformed. On top of that, metal can be uncomfortable against the skin. Our elastic button extenders are a better choice - they don’t rust, don’t deform, they are soft and machine washable for long-lasting comfort and convenience. Adds Extra Space: Each extender adds 1.3-2.5cm (0.5-1in) of extra room, depending on the loop size. Designed to fit buttons with a 10.2 mm (16L) diameter. Note: measure your shirt button to ensure fit, as sizes vary and consider three key factors before purchasing: 1. button size (diameter), 2. loop length (how much extra room you need), and 3. colour/design. Comfortable Fit with Ease for Men & Women: Struggling with tight shirt collars or cuffs? C2 Collar and Wrist Extenders (cufflinks) instantly add extra room - no sewing or tools required. Just fasten and go for a more relaxed, tailored feel throughout the day. Package Includes: 5 easy-to-fasten mixed-size white & blue buttons designed for versatile use and a personalized fit. 2 Small (ideal for subtle, stylish changes to collars or cuffs with a very slight size increase), 2 Medium (add about 2 sizes-perfect for expanding tight collars or cuffs), and 1 Large (offering approximately 3 sizes of extra room, for maximum comfort or as a central button replacement around the chest or belly). These extenders provide flexible solutions to fit your needs.
