Magnetic bra‑back extender that adds width for a more comfortable fit without sewing. Strong, easy‑align magnets close securely yet release smoothly for dressing. The 50 mm (2″) spacing fits many wide‑band bras and helps extend the life of favourite pieces during size changes. Choose white for a clean, discreet look under light garments. For best results, test on a scrap first and match tools to fabric weight and machine class for consistent results.
