Plastic Toothbrush Holder

Choose a shelf made of materials suitable for bathroom use, such as moisture-resistant or waterproof materials. This ensures the shelf can withstand the humid environment of a bathroom.
Self-adhesive toothbrush holders typically come with a strong adhesive backing that allows you to stick the holder securely to a clean.
Since you mentioned a self-adhesive option, make sure to follow the installation instructions carefully. Clean the wall surface before applying the adhesive to ensure a secure grip.
