ClearStream Billboards can be attached to your clear bins and are an inexpensive way to create sponsorships, give directions, or say a clear message. When clear bins have Billboard signage attached to them, visitors at your event are reinforced about where to place their waste items. ClearStream frames have slots to attach the Billboards. A Billboard Sign Kit has a sleeve which holds back-to-back 17” X 11” ledger size signs which can be inexpensively printed on an office copier for instant messaging.
