Clover Open Sided Thimble

While it may look like a tiny, finger iron maiden with a sunroof, this brass open sided thimble is quite a bit more comfortable than the old style thimbles. The open side is highly adjustable and easy to expand or snug down onto your finger for a unique fit while offering plenty of space for your fingernail. It helps to keep your finger from getting all sweaty to boot!

The medium is a good choice if you are looking for one to use on your thumb.

Great tool for basket weavers as well; save those fingernails when packing down reed!
