This luxurious 12.5" mid-length topper hair piece clips in easily and provides natural-looking layers that blend seamlessly to add length, boost body, and provide coverage just where you need it.

For best curling results, clip curls and allow them to cool. Once the topper is cool, the style is set and ready to go! 100% hand-tied fibers allow you to brush the hair in any direction you choose for the ultimate in styling versatility and an exceptionally natural look at the parting. Attaches comfortably and securely with four wig clips. Length: 12.5". Base: 3" x 4.75". Weight: 1.5 oz. NOTE: If you change the style using a heat tool, it will remain in that style until heat is reapplied to create a new one.
