I just got mine today...no removal tool. I'm going to email the company. If there's no removal tool, or instructions on how to remove the lens covers, I'm returning the product for a refund. The ONLY reason I purchased was because of the removal tool. Can you imagine trying to get those things off, and damaging the lens in the process?
It's not difficult. I've used them on iPhone camera lenses, they're pretty similar in design. The adhesive on some of the S21 lens protectors were horrible and tend to shatter as they're entire sheets of tempered glass. These individual lens protectors aren't bad at all.
