The OESD Perfect Pencil is a white, iron-away pencil that is visible on color and dark fabrics. It makes clear, neat marks that won't brush off like chalk when handled. Marks will be visible on the fabric until you iron it away, completely disappearing with no residue! To sharpen, simply pull on the string to refresh the tip. Test on fabric before use.*OESD items may not be sold on Amazon, Walmart.com or any other marketplace website.
