Hey ...just found out recently my old post .
Soo in case manueld12 is still looking for answer. All those tips are home made also, Those are all hamered,cuted, brushed ordinary nails .... the "holder" is from "mechano" toy i found somewhere...
About performance ..it works really great. I can set great range of heats mainly becouse of my own regulator. I can get like 30-40-50 degre and higher ... no over heating . And its also much much smaller than those wood burners ..its neraly size of ordinary pen. Soo if you are really looking for something cheap and great performance this is the way.
