0098 This is a first aid kit made of extremely durable plastic, making it virtually crush-proof. This kit is also waterproof and air-tight when closed making it ideal for boats or dusty areas. If using this kit on a boat, we suggest the insect sting relief wipes (2632). Also, red oil would be a great buy to treat sunburns. Both the insect sting relief wipes and the red oil will fit in the kit in addition to the products already included. This is our best kit for all your boating needs.
