Plane Sights™ R3241L Flagright Reflective Orange 4" x 32" reflective gear pin flags, R3241L 4x32" with 3/4" glass bead reflective on each side and "REMOVE BEFORE FLIGHT" printed on both sides. This flag was originally designed to meet the abrasion resistance, weatherability, and self extinguishing/flame requirements of our wide body and other long range business jet OEM customers. They're flame retardant and meet the NAS technical specifications for remove before flight flags. (but not the color specifications for obvious reasons).
If you're looking for a super durable gear pin flag that's designed for the abuse of quick turns and tight stowage, this is your ticket.
