Made with a polyurethane shell and a polyester lining, the 6 inch wide Spiderman Studded Zip Around Ladies Wallet may have also had its genes tampered with...or exposure to a radioactive spider. Either or, really. I also wouldn't try using the Spiderman Studded Zip Around Ladies Wallet to scale any walls either to spite the fact that this groovy wallet has metal spikes. Still, the inside's fleet of pockets and sleeves should be more than enough to compensate. Yeah!
