This is a set of two eco-friendly scrubbers made from 100% natural hemp fiber and 100% cotton, gentle on the earth. The hemp twine uses vegetable oil, so it doesn't have the smell of machine oil. Why not take a step away from sponges that release microplastics and switch to natural scrubbers that are kind to the environment? I actually use these at home, and they clean well without using detergent. It saves me the trouble of adding more detergent and rinsing away the foam, making dishwashing much easier. I use an iron frying pan, and these scrubbers clean it without removing too much of the oil from the surface, so they're gentle on the pan and I think it will last a long time. Due to the nature of hemp twine, it requires some force to clean the bottoms of cups, so I made one with soft cotton yarn. As you can see in the photo, it reaches every corner with light force, making it easy to wash. As for care, I recommend sterilizing them regularly by boiling. Boiling sterilization can be done in a small pot like a milk pan, with just enough water to submerge the scrubber. It's easier than you might think. The open weave allows for good ventilation, making them quick to dry and hygienic. Hemp Twine Size: Length: 10 cm, Width: 15 cm Cotton Size: Length: 8 cm, Width: 11 cm Please note that there may be slight variations due to being handmade. They will shrink when wet, becoming smaller than the sizes listed above. The beginning and end of the yarn are left long. As you use them, the knots at the beginning and end may loosen, so please pull the yarn to tighten them. Thank you for your understanding.
