A new tool to count your rows! These great rings were originally used in pen-and-paper roll play games, but are also perfect for knitters! The rings are made from stainless steel, they are shiny and durable. Each ring has a marker indicating the current count. To continue counting just push the numbers a bit inward and turn the numbered ring ? the clever design will make the numbers snap in place so it won?t get displaced.
