POLASK was previously available on Japanese crowdfunding site ‘Makuake’. POLASK reached the planned sales target on September 25, and the pre-sale ended. Despite the high price of 15,000 yen per bottle, it became a hit with sales of 13.2 million yen. On its Makuake page, the company successfully advertises the merits of titanium, such as its light weight, corrosion resistance, and the fact that it does not have the taste and smell of iron. On the other hand, the surface of titanium is specially processed to overcome the disadvantage of being easily scratched, which is a feature not found in other products. However, I think the reason it was a hit was the unique design of the specially processed bottle, with its seven colors and matte surface.
