One package contains 100 jump rings. These rings have been made by hand by me. I wrap the wire around inch size mandrels and cut the rings with a .008" saw blade. Then tumble them to remove burs and clean. Here are ring sizes needed for each of these popular weaves and the approximate rings per inch (rpi):

Byzantine:
20ga 7/64" (2.8mm); appx 30 rpi
18ga 9/64" (3.5mm); appx 24 rpi

European 4-in-1:
20ga 7/64" (2.8mm); appx 45 rpi
18ga 9/64" (3.5mm); appx 33 rpi

Turkish Round:
20ga 7/64" (2.8mm); appx 57 rpi
18ga 9/64" (3.5mm); appx 42 rpi

Full Persian/Foxtail:
20ga 11/64" (4.3mm); appx 26 rpi
18ga 7/32" (5.5mm); appx 20 rpi

Half Persian 3-in-1:
20ga 9/64" (3.5mm); appx 16 rpi
18ga 11/64" (4.3mm); appx 16 rpi

**Japanese 12-in-2:
Small Rings: 20ga 7/64" (2.8mm); appx 50 rpi
Large Rings: 18ga 11/64" (4.3mm); appx 21 rpi

**Parallel/Helm's Weave:
Small Rings: 20ga 7/64" (2.8mm); appx 7 rpi
Large Rings: 20ga 3/16" (4.8mm); appx 10 rpi
OR
Small Rings: 18ga 9/64" (3.5mm); appx 6 rpi
Large Rings: 18ga 15/64" (5.9mm); appx 9 rpi

**Dragonscale:
Small Rings: 20ga 9/64" (3.5mm); appx 34 rpi
Large Rings: 18ga 15/64" (5.9mm); appx 34 rpi

**Note that the Japanese 12-in-2, Parallel/Helm's Weave, and the Dragonscale all require two different size jump rings.
