Quality oval jump rings in 5x7mm size. Pack contains approximately 120 rings. We always recommend the use of oval jump rings in jewellery making. This is because with a round jump ring, gravity always takes the hole in the ring to the the wire threaded through, so if you leave the slightest gap, your wire may come away, whereas with an oval ring, gravity takes the wire to the bottom of the loop - away from the gap so makes for a more secure fitting. These rings are also available in other colours, and a smaller size is also available too.
