Clover one sided thimble

With an open top and sides, this adjustable metal thimble is designed to let your finger breathe to keep a good grip from both sides. The dimpled top helps hold your needle and keep your finger tip protected so you can apply enough pressure for any thickness of fabric. Suitable for people with longer fingernails, gently bend the arms of this thimble to adjust it to your finger size.

Two sizes available Medium and Small. I wear the small size (my finger measures 4.3cm if I wrap a tape measure around the end of my finger) so the medium is quite large.
