Waterproof PVC Material for Long-Term Use
Made of premium PVC material, our bathroom signs decor feature a good waterproof character for high-humidity environments.
Aside from that, the smooth surface also performs well for waterproofing. It keeps the water vapor out of the signs, helping the drops of water slide down easily when splashed onto the signs.
Unlike bathroom signs with wood frames, our virtual printed frame PVC bath decor will not be corroded by the water, nor will they burst with a bad smell.

Reuseable Double-sided tapes provided - convenient and simple to hang or remove, without destroying or scratching the wall/tiles.
