HEIMPLANET THE CAVE HEIMPLANET Dome Tent Includes an air pump, as shown in the photos. Stored indoors. Ready to use as soon as you inflate it. There are five valves on the tent, and you need to close four of them. Connect the pump to one valve and inflate; it takes about 3 minutes to set up. I've cleaned off as much dirt as possible, but since it was used outdoors, there may be some dirt on the contact surfaces. There are no holes in the tent, and there are no air leaks. Taking it down also takes about 3 minutes, just by opening the valves. Size is for ~3 people, but please check the manufacturer's website for details. I used it with care, so I think it's relatively clean, but there are some minor dirt and stains from outdoor use. Please check the photos. Please understand that this is a used item.
