Thank you for viewing! These are acrylic scrubbers made by my 90-year-old grandmother. She has always been skillful, and now she makes them to prevent cognitive decline. Diameter: Approximately 10-11cm, with a loop. There may be variations depending on the type of yarn and individual differences. Regarding shipping methods (acrylic scrubbers only / comment required in advance): ■ For an additional 80 yen, we can change to Mercari delivery. For 2 or more sets, we will switch to Mercari delivery at actual cost. ■ Up to 8 pieces, standard mail is the most economical. ■ The maximum number of pieces per package is 22.
