IRON Heart Silver925 chain from a famous brand. Handmade and high-performance, with the selling point that it can actually be used as a motorcycle chain. The actual craftsmanship is truly superb. The retail price is 150,000 yen. Handmade with a magnificent construction, it looks cool too. Silver chain. The last photo shows it lightly polished after being boiled in a special liquid. I tried polishing half of it, and the other half I wiped with a polishing cloth, which made it look whitish. However, it became uneven, as expected from an amateur, so I didn't want to polish it too much, but I did it so you could understand its quality.
