I bought these and kept them in the bag without using them. They are a set of two. Some of the suction cups are slightly warped, but they are still usable. The suction cups look dirty, but that's how the product is. You can replace the bags many times with unused plastic bags, so it's eco-friendly. 【Product Description】 【Material】Made of flexible ABS material, it can be closed tightly, and the opening and closing can be done smoothly with the knob. You can easily put in and take out plastic bags. You can attach a plastic bag and close the mouth when not in use, and since a triangular corner doesn't take up space, you can use it even in a narrow sink. 【Easy to Match】Rounded shape along the corner, easy to fit in the sink. If the suction cup in the middle doesn't reach the wall, you can use the auxiliary parts to reach it. However: Please note that it cannot be used in a right-angled sink. 【Odor Prevention】Odor is hard to leak! You can open and close the lid with one touch, so you can prevent odors from leaking and keep your kitchen clean. And the lid and suction cups are detachable, so you can easily remove and wash them. Very hygienic! 【Installation Notes】A hook is attached to the bottom to prevent the plastic bag from slipping, but if the plastic bag doesn't have handles, it's easy to fall if it's too high, and it's easy to accumulate if it's too low, so please attach it according to the length of the plastic bag before sticking the suction cups. 【Clean Sink】The height is adjustable, so the bottom of the bag doesn't easily come into contact with the sink, allowing for good drainage and clean use. You can close the mouth with a snap, so you can't see the garbage, and the inside of the sink is also clean.
