Hamanaka Single Crochet Hook Size: 4.0mm Model Number: 7/0 I threw away the packaging, so I'm using details saved from the internet. I will also send a set of Hamanaka yarn. The yarn on the far left in the photo was purchased at Daiso and I won't be using it anymore, so I'll send it along too!!! Please feel free to contact me if you have any questions.
