BIC Lighter Waterproof Cap

Simple waterproof cap for a normal size BIC Lighter.Printed in TPU 95A, other TPU should also work. Made this for the backup lighter in my backpack so it does not get wet when raining. Tested submerged in a few inches of water with the cap on for 30 minutes (sticker on the lighter was removed) and lighter was lighting instantly when removing the cap.
