I bought it because the material was described as stainless steel in the item description of SB - 50H, but unfortunately it was like SK steel (carbon tool steel) like the replacement blade of ordinary cutter knife. I wanted to know the reason for such a situation and confirmed the description of the manufacturer's website, but it certainly became a misunderstanding description. I think that it is better to improve it including that. Also, I think it is very difficult to replace package photos every time, but I hope that you can respond if possible. I think that there was no misunderstanding like this time if it was replaced. Since the product is a consumable item, I will stock it for the time being. Therefore, this time it is not a used impression.
