We have Toho size 11 seed beads. They have a diameter of 2.2mm and are sold in a flip top box or ziplock bag containing approximately 1250 beads weighing 11 grams depending on the finish.
Takumi beads have holes that are 15% bigger than traditional Toho seed beads. Useful for designs with lots of passes of stringing material through the beads or use with thicker stringing material.
Tested with 0.15mm Wildfire and a size 11 needle these beads take 10 passes of thread. Change to a smaller needle and you may get a few more!
