Thank you for viewing. This item is listed on auction. The auction will end in the 20:00 hour the day after the first bid is placed. I stored this item after purchasing it without using it. The weight of the cone core seems to be about 28g, so I think I bought 50g of yarn, but I don't remember exactly. If you are concerned about the weight, please refrain from purchasing. Shipping is scheduled for January 5th. Thank you for your consideration.
