Haters gonna hate. Give them something to talk about. Hard rock from the Rockstar collection by Hidesign is handcrafted using vegetable tanned leather. This back pack is made with shiny wax filled leather, contrast zips and black nickle hardware details. Products handcrafted with calf leather have pebble like texture, with unique stretch marks, scratches and scars on its surface when left in its natural state. It in no way affects the quality of the product.
