I noticed some of the same items are available on both websites (leathercrafttools.com & goodsjapan.com) but the prices on leathercrafttools.com are generally noticeably cheaper for an identical item.
As you will see from below examples, there are many more if you search both websites, the prices for identical items are much lower at leathercrafttools when compered to goodsjapan.
My question is, are the tools at leathercrafttools cheap knockoffs or is goodsjapan simply overpriced???
