This is the more versatile style of Steripen since it has the gasket that allows use in smaller bottles than many other Steripens. Has the screen to easily tell status of treatment. Works absolutely flawlessly. Includes everything in the pic below (not my pic) - I'll post pics tomorrow. https://www.freshwatersystems.com/p-...JVEaAkR58P8HAQ Has been carefully used on a few trips and has VERY light surface scuffs from packing in pack without the neoprene case. I can't get the scuffs to show in pics. I am also including two new lithium batteries - well almost new: I used it this past weekend. $42 shipped ConUS, Paypal only.
