Item description according to supplier: The open thimble is a handy little sewing accessory because you can wear it as a ring on the middle or ring finger. Having nails does not stop you from using it! Ideal for pushing the needle through the fabric without risk of injury. The notch on the side allows the needle to be pushed sideways. The spiking on the outside prevents the needle from slipping. Made of high-quality nickel-plated brass, this thimble is ideal for all your sewing, embroidery, patchwork, or even DIY work. BOHIN offers thimbles in diameters from 14 mm to 18.80 mm.
