Since the handling of NIKKO made dimple key wire tablet was canceled, I bought it as an alternative. The basic structure is the same, wire diameter is the same. Weight is 198 g made by NIKKO, 176 g made by GORIN. The thing surprising when looking at the thing is covered with colored transparent resin so you can see the inside metal wire, but its wire diameter is only about 5 mm. The wire diameter of 12 mm in the catalog notation represents the resin outer diameter, and the metal wire inside is used much thinner than that. Incidentally, the metal wire diameter in J & C JC - 020W with a nominal outer diameter of 10 mm with a price of half price is about 5 mm. Wire shielding as a crime prevention measure has significance in the metal wire diameter inside the resin than the outer diameter of the resin so it is safe if you chose a color scheme that you can not see the metal wire if possible at the time of purchase. Since the key attached to the wire lock has the same color as the lock, sorting is easy when multiple keys are attached to the holder.
