Toho beads are one of the most popular seed beads used in beading and jewelry making. Their uniformity of size and shape makes them a perfect fit for almost any project. TOHO beads are machine manufactured in Japan. TOHO beads are made of glass. TOHO beads have a larger hole than those found in most beads of similar size. A larger hole allows for multiple-pass stringing, and more creative options in your beadwork.
