i must be the glupen king cos ive had some emails about making them
so here it is
step 1 - unscrew the lid off the glue pen and empty that shit away but dont waste it put it into a jar for future use.
step 2 - the lid/nip consists of three parts, the screwy ringpiece, the circle of material and a sort of plug that wedges in behind it, just push down on the top and it shud pop out.
step 3 - throw away the bit of material as its not that great mine was to thick for the paint and left bad streaks
step 4 - get an old t shirt, or anything made of thin cotton (i used my old work shirt fuckin cunts!) and cut a whole about the size of a 2p (bout an inch wide)
step 5 - from seeing how the other bit of material was in place its simple just put the material over the bung and put it back up tight put it on the marker with ur chosen juice and vallah!
(this is how all the glue pens ive used have been constructed other models may vary, contents sold seperatly, please ask the carpet payers permission before you make the mod, skirmfirm industries will not be held responsible for any mad drippy handstyles that may result from the use of this item)
