If you purchase 2 or more sets, I will change the shipping to Mercari delivery. These are acrylic dishcloths, approximately 9cm in diameter and 3mm thick. They are eco-friendly dishcloths knitted with antibacterial and deodorizing acrylic yarn. (As these are handmade, there may be slight variations in size.) They can also be used as coasters. If you prefer them without a hook, I can make them for you, but it will take some time, so please let me know. For dishes and pots with oil stains, it's honestly better to use a sponge and detergent, but (f^^;) for dishes without oil stains, tea stains, coffee rings, etc., they can be cleaned with just water. For cleaning the bathroom, I alternate between using detergent and not using detergent for cleaning the bathtub, but the amount of detergent I use has decreased, and I'm still maintaining cleanliness! On days without detergent, the dirt comes off better if you wash it immediately after running hot water♪ You can hang it in the washbasin and quickly clean it with the water you're waiting for to wash your face. Washing the washbasin with detergent about once a week will help maintain cleanliness! To care for the eco-friendly dishcloths, if you don't mind, you can put them in a net and wash them in the washing machine, then hang them to dry, and they will last longer(*´∇｀*) Please let me know if you are purchasing multiple items. I will offer a small discount for combined shipping.
