Anybody have good recommendations on barbell eyes to use if you want jigs that end up weighing around 1/8 oz?

Most of the materials I can find online either don't give the weight or weigh significantly less than 1/8 oz. Most give a size, but no weight.

The 1/4" or 5/16'' I-Balz look good, but I can't seem to find a weight for them: https://spiritriver.com/materials/tying-essentials/beads-cones-eyes/i-balz-tm
