Thank you for viewing. I used it about twice after purchase. It's a product that's close to new and has been cleaned and disinfected with alcohol, but there may be some cut hair that couldn't be completely removed and is stuck in the gaps. Also, please note that we are not responsible for any problems caused by this product after purchase. If you understand this, please consider purchasing.
