its industrial supply.
wich means that.
labels come in a variety of forms and are made for utmost permanence...meaning if i have heat enabled labels and put them up on a metal pole during summer time with the correct bonding ink... it not only adheres for a duration of 1-2 years , the ink also stains the underneth surface..wich in theis case is metal and lasts about four weeks if the sticker is "scrubbed" off.
i made a thread in a the yard a minute ago about industrial paint markers but its gone i think.
and inks come in so many flavours its redic'
i've had a push button ink roller
label maker
super huge pilot marker.. bigger than the ultrawide
