I recently went on a sightseeing trip to South Korea and bought three of these in Japan to take with me. I only used them once during this trip. I don't think I'll be going to Korea again, so I'm selling them. These are plugs for using Japanese appliances in South Korea. Set of 3 Type C conversion plugs, 250V, 6A compatible. - Type: C type - Voltage: 250V - Current: 6A - Quantity: Set of 3 Thank you for looking.
