A+ Positive Blood Type 'Super-Lumen' Glow-in-The-Dark Patch

The new "SUPER-LUMEN" patches will outshine your existing GITD patches, and glow for up to 8* HOURS in the dark! Vanquest's "SUPER-LUMEN" Glow-In-The-Dark patches will outshine any of your GITD patches, and glow for HOURS in darkness! Our R&D has finally perfected the "SUPER-LUMEN" formula: It is super bright, easily charged, and can glow for up to 8* hours in the dark! This 2.25" x 1" blood type morale patch indicates Rh factor in both symbol and text. Rounded corners decrease snagging, and hook fastener sewn on the back. Perfect for identifying your gear, day and night. *Please let your eyes adjust to the darkness, and use your light-sensitive peripheral vision to observe the glow as the "rod" photoreceptor cells on the peripheral part of your retina are more light-sensitive than the "cone" cells at the center of your eyes.
