This soft, comfortable blue thimble has a hard tip to prevent needle penetration and large openings on back to allow your finger to breathe. The thimble is very comfortable to wear and once on it stays on not simply dropping off like a standard thimble. The thimble completely protects your fingertip while allowing your finger to breath for extended sewing sessions! Use to cover index or middle finger. Size: approximately 1.5cm x 2.4 cm
