Our Blonde Remy Silky Straight Closure is on an undetectable lace. Our closures are 100% human hair and 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 and 5 x 5. Like all of our hair our closures are good for repeated use.
