Black Basic Swim Cup Inserts Size 20/40B

These wafer-thin smooth laminate foam swim cup inserts are designed to blend neatly into swimwear for a clean, comfortable finish. They’re a practical choice when you want light shaping and coverage without adding bulk, making them useful for swimsuits, sportswear, activewear, and even evening wear projects.

Because they are sun and chlorine resistant, they’re a smart option for garments that need to hold up to pool and outdoor use. The smooth profile helps them sit discreetly inside your garment, and the black color makes them easy to pair with darker fabrics.
