Thank you for viewing! I carefully pack all items! Discounts are available for followers ✨ Instant purchase welcome ☘️ Bundling welcome ☘️ #kana☆ProductList☆ ★ Breathable neoprene (latex-free). Easy to attach to any point on the outside, using adjustable Velcro. ★ It simultaneously achieves three things: elasticity to freely adjust the tightness, durability to last even with intense sports or frequent washing, and lightness so it doesn't feel heavy even when worn for long periods.
