4mm JUMP RING MIX Open 4mm x 0.7mm with Storage Box
Jump ring mix that includes six different colors of open jump rings including:
*Shiny Silver Plate
They measure 4mm in diameter x 0.7mm thick.
You receive approximately 230 pieces per color. All are conveniently stored in a plastic storage box which is included. I use these myself and in the spirit of full disclosure, I find that the lids on these boxes don't always want to stay closed. When not in use, I would recommend keeping those that don't stay closed sealed with a small piece of washi tape or the like. Just an FYI, so there are no surprises.
Other sizes available in the store.
