The bracket is 2.5mm thickness of pressed steel. Japanese Standard Series style , the caster outlook is very attractive with a very shiny Niken coating. Rubber wheel quality is good and very wear resistant.

Shiny Nickel coating enhances rust and corrosion resistant. Steel hubs are soldered with the cast-iron core so it is hard for dust, water and silk to intrude the ball bearing and shaft. Thus lessen the needs for maintainance.
