P431314 Prym Open Tailor’s thimble. The tailor’s thimble, unlike normal thimbles, dispenses with the closed dome and therefore has dot shaped notches on the side, allowing for lateral sliding of the needle. The thimble from silver coloured steel is available in sizes 16 mm, 17 mm and 18 mm. A rim at the lower edge of the tailor’s thimble prevents slipping of the needle and provides additional protection. 431314 18.0mm 1pc
