Miyuki Tilas, with their distinctive flat square shape and two-hole design, originate from Japan and are highly regarded for bead weaving due to their uniformity and the ratio of hole size to bead size. These beads measure 5mm in width and 1.9mm in thickness, featuring two parallel holes each 0.8mm in diameter. A single tube typically holds about 7.2 grams, which translates to roughly 75 to 80 beads, depending on the specific color and finish.
