LK Clear Film 3-Pack
It never hurts to have extras and that's why we're recommending the LK (Lightning Knight) Clear HD Film 3-pack for the Pixel 3. And while this isn't a strong or durable glass, film screen protectors still do a pretty good job.
Each LK protector is a military-grade film that's designed to last. They have self-healing properties, each layer is tough and designed to absorb impacts. This tech-skin is resistant to scratches, punctures, and will prevent screens from shattering during accidents. Not to mention it won't yellow over time like some.
If you mess up the install simply take it off, wash it, and try again. Plus, you'll get three in case you're prone to accidents or keep messing up. The third times the charm, right?
