Our Brazilian Curly Closure is on an undetectable lace closure. Our closures are 100% human hair. Our closures blend naturally giving the appearance of the hair growing from your scalp! Each individual hair has been hand tied to a lace base material that allows you to part the hair anywhere. Closures are available in sizes 4 x 4, 5 x 5, 6 x 6 and 7 x 7. Like all of our hair our closures are good for repeated use.
