This CLOVER roulette is perfect for marking patterns. This item was found while organizing my grandmother's sewing supplies. I believe it is unopened, but please be aware that it has been stored for a considerable amount of time. Also, I have not opened it to inspect the actual item. Please note that the outer plastic bag has some dirt on it. I am very sorry, but I am not very knowledgeable about sewing, so I may not be able to answer many questions. Thank you. - Brand: CLOVER - Type: Roulette - Handle Color: White
