Size... Approximately 11.5cm long, 7cm wide Thickness... Approximately 8mm Colors... Gray, Light Gray, Deep Green, Deep Blue This is a set of 4 handmade acrylic scrubbers. They are knitted with 100% antibacterial and deodorizing acrylic yarn. They are knitted with a method that creates thickness, so I think they are easy to use with a moderate thickness. The front and back have the same knitting pattern. They have loops and can be hung. There may be slight variations in size and knitting. Please understand that these are handmade by an amateur before purchasing. Acrylic Scrubber Eco Scrubber Handmade Kitchen Cleaning Supplies
