This is the cardboard core from the industrial stretch film that my grandfather uses to package and ship vegetables. ^_^ He usually throws them away as recyclable waste, but I thought they could be used for children's crafts or DIY projects like cat towers and scratching posts, so I'm listing them on a whim♪ They're quite sturdy and don't seem like they'll crush easily! Length: 48.7cm Diameter: 4.8cm Total weight: 4.5kg (0.25kg x 16 cores, box 0.5kg) Shipping via Yu-Yu Mercari Mail Yu-Pack. *Please note that there may be slight variations in length, diameter, and appearance as they are measured by hand.
