These items were used in a barber shop that has closed down and were in active use. The bottom three appear to be a single unit, while the top three seem to have replaceable blades. Individual sales are possible at 1,500 yen per item. I am not an expert, so I cannot confirm if they are usable and will sell them as junk. Please purchase only if you understand this based on the images. Feel free to ask any questions in the comments. m(_ _)m
