This is the 8th model in the Gomez Type 8 series, a steel dart set designed by professional player Yanmar (Yuki Yamada). - Model Name: Gomez Type 8 - Material: 95% Tungsten - Length: 40.8mm - Barrel Weight: 21.5g (including point) - Maximum Diameter: 7.6mm - Accessories: Condor Shaft (integrated flight) This is a torpedo model before it became a straight barrel, with an octagonal shape at the rear. Personally, I liked this model among the Gomez series because the grip is relatively stable. Thank you for looking.
