C2 20L Pack of 2, Black Cufflink Extenders

No Rust, No Warping: Metal extenders can rust your shirt if left on during washing. 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. Comfortable Fit with Ease for Men & Women: Struggling with tight cuffs or shirt collars? C2 Wrist Extenders (cufflinks) and Collar instantly add extra room - no sewing or tools required. Just fasten and experience a more relaxed, tailored feel throughout the day. Up to 1 Shirt Size Extension: These extenders feature an elastic loop that adds about 1 shirt size (1.75 cm / 0.7 in), perfect for lightly expanding cuffs and collars with a very slight size increase. If this is too small, larger loops are available in our store, including Large loops that extend up to 3 shirt sizes. Cufflink and collar buttons are available in multiple colours, and a mixed pack (including various sizes and colours) offers flexible options to suit your needs. 20L Size Buttons: Package includes 2 easy-to-fasten black buttons in 20L size (12.7 mm / 0.5 in diameter). Make sure you measure your current shirt button diameter before ordering to ensure a perfect fit. We offer multiple button sizes. If this one is too big, look for the smaller 16L or 18L button extenders available in our store. Patented Design Made from Recycled Materials: Our patented, high-quality button extender offers a smarter, more comfortable alternative to generic options. Each piece features a durable, flexible elastic loop paired with a premium recycled resin button, designed to withstand daily wear and washing. A sustainable, reliable upgrade for your shirt.
