I already had a shaver I was using, but I bought this one to support the customer at their exhibition. After trying it 2-3 times, I packed it away with my moving belongings due to a job transfer. I recently found it and cleaned it with an air blower. It works without any problems. Since it's been a while, I applied liquid paraffin oil after cleaning. In the fifth photo, there's a shutter on the top of the main body that opens and closes. This feature allows you to rinse the outer blade with water after shaving without removing it. It's not brand new, but I hope to sell it to someone who can use it. Thank you.
