for me i must prepare the takasago brand of chain
it is also made from japan jst wat neo said that
it is not that expensive but the quality of the chain
is there...because there are rumor that there are so
many DID brand that out in the market that is made
in china "fake" it seems that no different from the original
im not against w/ DID but im just saying an advice to
guys....but if you can buy an original DID much better
but what im only saying is be careful to buy DID coz
there was a lot of fake DID now in the market.
