Ideal for menus, maps, labels, and low-light situations where reading glasses aren’t available.","KEEP ONE WHERE YOU NEED IT - Four cards let you stage backups in multiple locations. Store in wallet, glove box, pack, or emergency kit so you’re never without a simple ignition option.","SLIM, DURABLE, ALWAYS READY - Thin design fits like a credit card and won’t take up space. Flexible plastic resists cracking and handles everyday storage in pockets, kits, and gear bags.","SIMPLE TO USE WHEN IT COUNTS - Angle toward direct sunlight and adjust distance until the smallest, brightest point forms. Works best with dry materials and steady positioning for consistent results."]
