Unused item. I believe these are bits for a Glastar G5 (Starlet), but I don't currently own the main unit, so I cannot confirm their suitability. Please refer to the size and make your own judgment. It may be difficult to see in the photos, but one of the two has a frustum shape (the one on the right in the second photo). I am also listing this elsewhere, so please forgive me if it sells out. #stainedglass #bit #routerbit #grinderbit #grinder #Glastar #G5 #Inland #Gryphon
