All of our custom wig units are constructed using the sewing machine, for longevity. You have the option to purchase bundles from us for wig construction, which we highly recommend. We also offer a service where you can send in your own hair extensions for construction. All units come with comb attachment and band. Oh, and how could we forget, all of our units are GLUE-LESS. No glue required to be installed. To get started on your custom unit, please fill out the Wig Form to begin ❤ Please allow 7-15 business days for your unit to be made and shipped!
