Adjustable straps? I've been visiting this forum for a little over a week. I'm OBSESSED with full lace human hair wigs!!! Two weeks ago I ordered my first full lace human hair wigs. It's an 18 inch body wave full lace human hair wigs. I can't wait until it gets here! I emailed him last night, and by this morning I had received a response from him. I want to order two full lace human hair wigs from him by Friday. When reading the catalog he sent me, I noticed that the specifics for many of his units included adjustable straps. My question is: What are the adjustable straps for? What are the advantages? Do any of you have them and are you satisfied with your units?My unit cost me over $500, so if I can find a cheaper unit of good quality, of course I want to try it.
