WIKHOSTAR Toilet Brush Silicone Toilet Quick Drying Cleaning Brush Wall Mount Gap Brush with Holder Tool Bathroom Accessories

The toilet brush is assembled from 4 parts, which is not mentioned in the description. It unscrews when used. At some point the brush will fly into the drain. I don't want to risk it, so I throw it away.

As in the photo. Everything is super, just need to make sure it doesn't unscrew during cleaning.
