Extra long stainless steel rods allow you to make multiple granny grids at the same time, increasing knitting efficiency. These are long enough for a stack of even bulky granny squares, if one wanted to use them for that. Perfect size stainless steel, if the project you are working on needed more rods than the blocking board came with and these were perfect. The rig plugs are also made of high-quality stainless steel, so they are rust-resistant and won't bend or break easily. The steel needle set comes with a storage case, making it very convenient to use steel pins wherever you want! Give as a gift to more people who use crochet blocking boards and knit more great crafts together. package included: 16 x 15cm (5.91inch) stainless steel rads 16 x 10cm (3.94inch) stainless steel rads 1 x storage case (random color)
