Closures, frontals, and glueless
What the supplied notes actually say.

Closure wigs in the brief use 2x6, 4x4, 5x5, or 6x6 and are described as having less parting space. Frontal wigs use 13x4, 13x6, or full lace and are described as costing more, with ear-to-ear parting.
Closure installation and frontal installation are each supplied at ₦7,000–₦16,000. Those are service fees, separate from the wig.
Glueless is supplied only as a note: usually ₦5,000–₦20,000 more than the same style with glue. It is not confirmed for every wig, and it is not itself a wig price.
