Hey Lillen,
Our Fang cover is particle but the Mean and Strike Machine(international piece) actually was a new formulation in a reactive form. It was designed with larger resin/reactive pores which was intended to grab in thicker oils of today but would offer a stronger backend reaction compared to other particle covers at that time. Hope this helps some...
