A3Disc had 40 10th anniversary Z GLO buzzzes to sell, we have 23 left as of this post available at league tonight for $25.00. first come first serve. no sales until i get to league. Only 1000 made and then sold to the MDGO clubs. fundraiser for DGLO. the 2 biggest differences between this disc and the 10th Anniversary buzzes released earlier is that they are GLO discs and they are backstamped with the DGLO stamp on the back.
