Peace, mercy, and blessings of God be upon you. This is a Tymo thermal brush device that does the same as a hairdryer but without sound. To clarify further, search for its name on TikTok. Used for less than a month. I bought it from Amazon for approximately 370. The reason for selling is that it didn't suit my hair. Its use is clear, and everything is shown in the pictures. I will sell it for 210, negotiable reasonably.
