All Sticklers™ fiber optic cleaning products are manufactured by MicroCare LLC of New Britain, Connecticut, USA. As such, and like all MicroCare products, all Sticklers™ products have an unlimited shelf life when properly stored. Proper storage is defined as in a cool, dry location, out of direct sunlight, and off any concrete floors.
Every Sticklers™ product has a lot number on the package. The date of manufacture is embedded in the lot number. The first two digits represents the year in which the product was made (e.g., lot number 22182 was manufactured in 2022). The last three digits represent the day of the year using the Julian perpetual calendar (e.g., 22182 was manufactured on the 182nd day of the year, which is July 1st).
If you have any questions about the lot codes or shelf life of Sticklers™ products, please contact your Sticklers™ representative or contact MicroCare headquarters directly.
