Theres nothing like classic gaming on original equipment. Dont let 28 years of grime, spit, and dirt stand between you and your favorite game. Blowing into game cartridges was fine when we were eight, but now theres a better way with 1UPcard cleaning kits. This newly manufactured kit contains one NES Compatible Console Cleaner, three 1UPcards, and cleaning fluid to bring your game cartridges back to life quickly. The Console Cleaner uses a micro-abrasive material to remove corrosion, dirt, and grim from the contacts but not any metal. While the 1UPcard restores old school games for legendary systems by cleaning the pin connectors in a flash without leaving fuzz. Extend the life of your games by removing the build-up of grime, carpet fibers, regular dust, and even gnarly cheese puff dust. 1UPcard products are proudly assembled in the USA for people who love gaming as much as we do.
