This item requires you puncture the plastic inside the tube. Most items made as such has a plastic flap that opens by pinching it or possibly inserting the device to inflate. We'll, you can guess what happened since I had to make my own hole. Yeap, I punctured the actual sink. I had to cover the small hole with tape to be able to use it. As you can see the sink didn't inflate smoothly like you see on the advertisements. Not sure what I could've done to get a better outcome.
