Material: 100% Acrylic Size: Approximately 13 x 13 cm Everything is handmade. I was selling in stores for over 20 years, but now I'm on Mercari. They're praised for cleaning well, and I had many regular customers in my stores. They're excellent for not only washing dishes, but also cleaning sinks, bathrooms, and even washing cars. This is the medium size, but I also offer small and large sizes. The large size is recommended for cars and larger items. #AcrylicScrubbers #Handmade #ProvenTrackRecord #CleansWell
