Honestly mate because it’s one of the best , said it before it’s the cleanest, smoothest gear , ok it’s slightly more per bag but pure and spray is basically what everyone is after when they discuss skim imo but they just don’t know it , I don’t mean that in any egoistic way too , I mean I’ve tried them all now and conclude they are the top 2, at £8.50 a bag most who buy there own materials and try them would agree , but the catch is unfortunately it’s pallet order only , it’s just the way it is mate.
