Here's my in house designed and made LED LargeBadge.
These are ideal as conbadges for those who want to get noticed.
Had one customer get screamed at from across the room "THAT'S A JENCEN BADGE!!!!!"
How much more noteworthy can that be? ^_~
Made from layers of 3mm acrylic it's 75mm wide and 112.5mm tall
All my badges come with Colour changing LED's now but you can pick a static colour for a small fee ^_^
Large Badges are £25 Plus shipping.
