Please understand that this is a used item stored at a private residence, so please only purchase if you are comfortable with this. Please refrain from purchasing if you are sensitive to such matters or if you are seeking a perfect item. I believe there are no significant flaws, but please understand that perceptions may vary. It is 100% cashmere, so it feels soft against the skin, and the GG pattern makes it immediately recognizable as a GUCCI knit hat. The color feels slightly softer than in the photos. The cashmere texture doesn't quite come across in the photos. I don't have many opportunities to use it due to my busy work schedule, so I hope it will be used frequently by someone who will appreciate it. Regarding the size, 21cm seems to correspond to M, but please confirm this on a website or similar before purchasing.
