If you purchase 2 or more sets, we will change the shipping to Mercari delivery. These are eco-friendly scrubbers, hand-knitted with antibacterial and odor-resistant acrylic yarn. Small size: Approximately 11cm in diameter Large size: Approximately 12cm in diameter They have gaps, so they dry easily. (Please note that there may be slight variations in size due to the handmade nature of the product.) How about using them as Christmas tree decorations or Christmas garlands? For dishes and pots with oil stains, it's honestly better to use a sponge and detergent, but (^^; for dishes without oil stains, tea stains, coffee rings, etc., they can be cleaned with just water. For bathroom cleaning, I alternate between using detergent and not using detergent for cleaning the bathtub, which reduces the amount of detergent I use while maintaining cleanliness. On days without detergent, the dirt comes off better if you wash immediately after rinsing with hot water. You can hang them in the washroom and quickly clean with the water you use for washing your face. Washing the washroom with detergent about once a week will help maintain cleanliness♪ If you don't mind, you can put the eco-friendly scrubbers in a net and wash them in the washing machine, then hang them to dry, which will allow you to use them for a long time (*´∇｀*) When they get worn out, use them for cleaning sinks, screen doors, and window sashes! A feeling of satisfaction when you've used them up (*´ω｀*) Please let me know if you'd like to purchase multiple items, and I'll offer a small discount for combined shipping.
