I got this container to accomodate my Adventure Paper logsheets. The paper is water resistant, but thicker than normal so I needed a fatter nano. Found these and they looked just fine...online. Bought a couple and found out the cap is an male screw. (cap screws into body of container. Most nanos the body screws into the cap, giving you an extra 1/4 inch of room. So, redesigned my logs to have double the length to sign, but only half the width. Bonus with these things: I could use a whole strip of log paper instead of a partial length. Have fun and watch out for traffic. As with all nanos, bring a pen. No way a scribing tool will fit in these agrivating things.
