About Double Seven Dual‑7 Design: The aesthetics feature mirrored “7” motifs from the creator’s name, placed one forward and one reversed. Main body crafted from titanium alloy with dual stainless‑steel base plates. Shimmer foil displays brilliant iridescent colors under light, with ergonomic contour for comfortable grip. Every unit is fine‑tuned by the creator before leaving the factory. Tuning‑Fork Haptic Response: Equipped with a brass tuning‑fork module for powerful hand‑vibration feedback and pleasant resonant tone. A recessed groove at the thumb contact point improves ergonomics. It keeps the reversible 6/8‑face feature, delivering huge potential for flat tricks while supporting 3‑dimensional manipulations. Both the tuning fork and shimmer foil are user‑removable. Exclusive Tuning: Custom magnet layout tuned exclusively by 77 EDC creator: 7×3 N35 magnets at four corners and 5×2.5 N25 magnets in the center. Optimized for flat‑surface tricks without sacrificing 3‑dimensional performance. Flip the magnet plate to switch inner‑outer magnet configuration, no plate replacement required. The stock ten‑hole plate supports flexible combinations: 6+6 / 6+8 / 8+8 / 10+10. Included Accessories: One set of high‑strength magnets: 8 pcs 7×3 N45 + 6 pcs 5×3 N45; one pair of gap‑adjustment magnet plates; anti‑slip ring for lower disc; two T6 Torx screws.
