2.15 ozt of sizes 7:21gf and 8:21gf, mixed together.
I’d use the 7:21 rings for a Snake chain, or possibly mixed with 6:20nb niobium rings for some lovely dainty Birdcage.
I’d use the 8:21 rings for some Half Persian 3-in-1.
Sometimes two (or more!) sizes get mixed together and I don’t want to fuss with tweezing them apart. These mixed batches are 10% off the least expensive size – sold as an entire batch only.
