The Mix'n'Ball Presser DLX creates a hard sealed surface on the pressed material which reduces oxidisation and protects the active properties of the materials contents but, most importantly, it creates a more desirable psychoactive effect. The reduction of residual moisture and increased density results in a longer, smoother session, whether you smoke or vaporise, it's the purest kind of high.
The Mix'n'Ball Presser DLX design was developed after hours of intense fiddling; trying to remove jammed hard cakes of material from 'other pocket presses'.
