CzechMates™ Picasso - Jet tile beads. 6x6x3mm tile beads with 2 parallel holes. Czech glass beads with two holes for innovative beading. True to their name, these beads originate in the Czech Republic. These two-hole Bohemian tiles are similar to Miyuki Tila® seed beads, but have rounded edges that help prevent thread from fraying. CzechMates also offer larger holes and a more durable molded-glass construction. Great for bead weaving!
