DURABLE: The sewer cover is made of high quality TPR material which is soft, lightweight and resistant to deformation. Easy to clean and reusable over time, the sewer lint catcher is large enough to hold hair and food waste. Note: Do not use on rough or dented surfaces, only suitable for use on smooth surfaces. Special design: The shower drain lint catcher has 4 suction cup bottoms that snap on steadily and do not move easily. The shower drain cover measures 15*15cm, so you can only use it on drains smaller than 4.7" (12cm). No more clogged drains: Our shower drain protector fits any standard bath drain and is guaranteed to catch every hair without interrupting the flow of water. The drain holes in the drain cover are clean and tight, so it drains very quickly. Easy to remove and install: Place the drain hair catcher in the appropriate sink and simply press down on the suction cups to keep it securely in place and you are ready to go, suitable for most standard bath and shower drains. To remove, simply grab the clumped hairs out of the trap. Household cleaning tools: Our drain hair traps can be used extensively in kitchen sinks, laundry drains, bathroom drains, sink and bath drains and anywhere you want to stop and capture residue.
