If you don't want to do without long fingernails, but often use a thimble when sewing, the adjustable thimble made of plum-blue plastic from Prym is the best choice. Because the fingernail is exposed at its opening on the upper side. The special punctiform notches on the tip and the ribbed notches on the side enable very precise needle guidance and prevent the annoying slipping of the needle. This thimble is also ideal for allergy sufferers who are sensitive to the usual metal thimbles, because it is made entirely of plastic. It can be perfectly adjusted to any size by briefly heating it in boiling water.
