1 liter (aka 34 oz) LARQ self cleaning water bottle! They just launched it this year and I only used it for 2 months, so I will ship in the original box and packaging with a brand new filter and everything it comes with. I love this bottle but ended up getting the smaller size (23 oz) so it fits in a cup holder. There are just some minor scuffs on the bottom shown in the first and last photo which you can easily cover up with a rubber sleeve, but it works completely fine!
