Just Funky releases 2 water bottles for 2021.
They're both semi-transparent dark blue, and hold 32 ounces of liquid. The left bottle has Sonic, Tails & Knuckles modern stock arts in action poses over individual but overlapping swirl backgrounds. It has a black lid with attached tab cover for the sipper part. The right side bottle has jumping-twist modern Sonic, but the design for him is so big, it cuts off at the feet. This also has the modern logo in white only wrapping around to the other side. That lid is red & has the same sipper/tab cover.
Both of these should be about 19.99 if you can find them in stores. They might be a Target item, or possibly Amazon. They're pretty large at 32 oz, and JF makes quality items/uses thick plastic etc. so 19.99 is probably about normal for a durable bottle. Both designs are nicely-Sonic themed & colorful. Either is an ok choice if you didn't already have something similar.
