The Wenko wash balls put an end to lint. Thanks to their special surface, the wash balls take up lint, wool, and hair right in the wash. Post-treatment with a lint brush or lint roller is unnecessary. They are also great for washing wool sweaters.The washing balls are simply placed in the washing machine. They are washable up to 60°C. The action of the detergent is amplified, and the washing machine and outflow stay clean longer.The balls are reusable. Simply remove the hair or lint before the next use. The package includes six wash balls.
