Size... Approximately 11.5cm long, 7cm wide Thickness... Approximately 8mm Colors... Gray, Deep Blue, 2 of each (the actual colors are a bit brighter) 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 so you can hang them. There may be slight variations in size and knitting. Please understand that these are handmade by an amateur, and purchase accordingly. Acrylic Scrubber Eco Scrubber Handmade Kitchen Cleaning Supplies
