Spigen Liquid Clear Case
Next is something that's the complete opposite of Google's case. Spigen is one of the most trusted case manufacturers on the planet. Consistently making amazing cases for almost every phone that gets released.
The Spigen Liquid Crystal clear case is always a fan-favorite. They do offer it in black, but clear is something most love. Especially if you're wanting to keep that "panda" look of the two-tone black and white Pixel 2 XL.
Spigen uses a durable, flexible, hard yet soft TPU material. It's essentially a plastic infused with rubber for the best of both worlds. Most cases use TPU, and Spigen typically makes the best ones on the market all at an affordable price.
