Curling iron, unused

I'm selling this because I opened it but never used it and forgot about it! The box is not included.
I'm not very knowledgeable about hair irons, so I don't know the exact size, but measuring with a ruler, the diameter is approximately 3cm.

As far as I remember, the price was 3,000 yen.
- Type: Curling iron
- Color: White/Gray
- Power cord length: Approx. 1.5m

Thank you for looking.
