I gather you are seeking something that falls into the black rubber style that adheres to the surface of the bumper, correct?
Example of one for your model year that appears to get pretty good buyer reviews: https://www.amazon.com/Auto-Accesso...d16d8&pd_rd_wg=n8YyN&pd_rd_i=B073J29R6V&psc=1
Accessories like this is something I would be careful to review buyer reviews before buying from an Amazon listing.. but the one I linked above gets really good 4 and 5 star reviews, and no 1 stars at all, with a reasonable number of reviewers and no signs of the merchant "packing the reviews" .. which is a good indicator. Only possible concern is I see it is a composite set of reviews for this suppliers products for several different Honda models. Actual CRV owner reviews appear to be strongly positive.
