A Zencraft-made winder made of paulownia wood, convenient with a timer. Currently sold by Matsuda Kiribako, who took over from Zencraft. Here's the URL of the current product for reference: [Yahoo! Shopping] Matsuda Kiribako Wind... https://store.shopping.yahoo.co.jp/matsudakiribako/yurikago.html It moves like a cradle, not a rotary type. The included sponge has slightly deteriorated due to long-term home storage, but can be replaced with a regular sponge. Please purchase only if you understand that this is an old item. Thank you for looking.
