This event badge holder was used commonly at Apple Education events throughout the 2000s. This version is black nylon and accommodates a 4×3-inch badge. The front uses a Velcro pocket closure with a zipper compartment inside that can hold business cards or credit-card-sized items. The back of the badge includes two loops designed to hold pens.
This example is black with a white Apple logo printed at the top-center of the front.
