If you purchase 2 or more sets, I will change the shipping to Mercari delivery. This is a set of 8 eco-friendly scrubbers, hand-knitted with antibacterial and odor-resistant acrylic yarn! Each acrylic scrubber is approximately 8-9cm in diameter and about 3mm thick. (As these are handmade, there may be slight variations.) While it's true that for dishes and pots with oil stains, using a sponge and detergent is more effective, these scrubbers work great with just water for dishes without oil, tea stains, and coffee rings. For cleaning the bathroom, I alternate between using detergent and not using it for the bathtub. This reduces the amount of detergent I use while maintaining cleanliness. On days without detergent, rinsing with hot water immediately after washing helps remove dirt better. You can hang them in the washbasin and quickly clean with the water while waiting for the water to heat up for washing your face. Washing the washbasin with detergent about once a week will help maintain cleanliness even more! To care for the eco-friendly scrubbers, if you don't mind, you can put them in a net and wash them in the washing machine, then hang them to dry. This will allow you to use them for a long time (*´∇｀*) When they get worn out, use them for cleaning the sink, screens, and window sashes! You'll feel satisfied when you've used them up (*´ω｀*) Please let me know if you'd like to purchase multiple sets, and I'll offer a small discount for combined shipping.
