Archangel Designer Woman Belt

I sent a notecard to the seller letting him know that there is a black box attached to the belt. Designers who use pre-made products do this to make the mesh their own. The box cannot be removed, even with the "invisible" texture included with the belt. In all the FP mesh I have purchased, I have never heard of this being done by an original mesh designer. The seller got back to me and once I let them know that the box wouldn't budge, he said that he would "try later". Well, two notecards and a week later, I have yet to hear back from the seller. Is this belt really his own design or he passing someone else's work off as his own thus the black box? Buyer Beware!
