A 13x4 lace wig in a bob style with loose waves, 16 inches in length, and made from human hair sounds like a gorgeous and versatile option! The 13x4 lace means the wig has a lace front that is 13 inches wide and 4 inches deep, allowing for a natural-looking hairline and parting space. The loose wave bob gives a soft, bouncy, and elegant look, while the 16-inch length offers a perfect medium length for styling flexibility.
