This thirteen-piece set of Rosebud medical dilators comes in a zippered vinyl case with red velvet lining. The sounds are made from chrome-plated steel and have a slender, straight shaft with the enlarged tip that gives this style of dilator its name and handles that offer a secure grip. Each dilator is a total of twelve inches long, offering approximately nine-and-a-half inches of insertable length. The dilators are graduated in size, and range from 1 mm to 13 mm in diameter (3 French to 39 French).
