The cups use a two-layer material, "Angel Slim Sheet (R)," with different firmness on the outer and skin sides. This prevents the bust from spreading sideways, creating a sleek look. The breathable "Angel Sara Through Cup (R)" provides a light and dry feel. The pad pocket uses a quick-drying material. The back is made of a breathable geometric mesh material with a flat design, making it less likely to dig in and less visible under clothing. The "NEW Angel Wire (R)" is used, which has a thin, flat, and curved wire at the front center. It is less likely to dig into the skin and cause pain. Volume is increased with fiberfill pads! The straps have adjusters for length adjustment. (Non-replaceable) The strap fasteners use a special triangular shape called "Delta Magic (R)," making them less likely to slip off the shoulders. ■ Bra Type: 3/4 cup ■ Hook & Eye: 2-row, 3-column: B cup, C (65/70/75/80/85/90), D (65/70/75/80), E (65/70/75), F (65/70) 3-row, 3-column: C (95), D (85/90/95), E (80/85/90/95), F (75/80), G cup ■ Bra Size Availability: B70 B75 C65 C70 C75 C80 C85 C90 C95 D65 D70 D75 D80 D85 D90 D95 E65 E70 E75 E80 E85 E90 E95 F65 F70 F75 F80 G70 G75 ※ Size availability varies by color. ■ Pad: Included ■ Materials: Polyester, nylon, others ※ D, E, F, and G cups have cup side boning. ※ C90-95, D85-95, E80-95, F75-80, and G70-75 sizes have two side boning. ※ The pattern may vary slightly from the image due to the cutting process.
