The bag is handmade, made to order by the same folks who brought to your the pee-to-portable water conversion system we posted earlier and it touts “self cleaning” feature. For 500 American dollars, you would secure yourself the backpack complete with goldfish, rocks, snails, and plants. Man, this had to be really hefty. I mean, water is heavy and the movement only adds more force on your back, but it will be worth the weight if it is used to show off your award-winning, prized goldfish. Though we suspect the fishes won’t be too excited about a walk in the park.
