Thank you for viewing! These are acrylic scrubbers made by my 90-year-old grandmother. She's always been skillful, and now she makes them to prevent cognitive decline. Diameter: Approximately 11-12cm, with a loop. There may be variations depending on the type of yarn and individual differences. Regarding shipping methods (acrylic scrubbers only / requires prior comment): ■ For an additional 30 yen, we can change to Mercari shipping. For 2 or more sets, we will switch to Mercari shipping at actual cost. ■ Up to 8 pieces, standard mail is the cheapest option. ■ The maximum number of pieces per package is 22. If you would like to combine items, please request a combined order or contact us via comment. We appreciate your understanding of handmade items. Thank you for your consideration.
