Like all of RAW's rolling accessories, this rolling machine is built with sustainability in mind. The base is made of durable, eco-friendly German hemp plastic with a long-lasting, double-thick vinyl rolling apron. The Raw 2-Way Roller is an adjustable roller that helps you roll both King Size and King Size Slim (110mm) cigarettes. The switch on the side of the roller allows you to switch from regular King Size to King Size Slim. Even if you're all thumbs when it comes to rolling, you can easily make machine-perfect cigarettes. It's also a handy accessory for someone who wants to prepare several in one sitting for a busy day ahead.
