This is a quality brass thimble designed with the modern woman in mind as it is open sided and adjustable. This means that your finger won’t get hot and sweaty plus your fingernails are not damaged as they can lay along the top. It is for a medium (average) sized finger but it is adjustable so that you can make it fit snugly. It has a dimpled surface so that needles & pins are less likely to slip. Perfect for any needlework.
