Brass Open Top Thimble (Gold)
A professional brass thimble with deep dimples. Thimble has an open top to accommodate long fingernails.
I usually prefer a leather thimble for stitching, but for certain stitching this open top metal thimble is the one I turn too. And in fact I have more than one of this exact thimble tucked away where I will need one. Only the smallest size works for me, although my hands are not particularly small.
