60s vintage orange plastic picnic canteen, double sided insulated cooler

Cute 60s retro carry along cooler with shoulder strap - this is clean and nice, and much more fun than a water bottle!

There are two separate 1.6 liter containers inside the insulated plastic case, which measures about 10" x 10" x 4 1/2" overall. It's marked Tukizo or Tuktizo, I think?
