Selected international designers, illustrators and artists are regularly invited to submit designs for this one inch (25mm) button badge series. Since 2004 B.I.O. (By Invitation Only) Series have been infrequent events but in 2012 the B.I.O. Series 12 release finally caught up with the years. Since then B.I.O. badges are released annually with B.I.O. Series 22 due in 2022, etc.
