This was the stuff my daughter had for her 2 precious gerbils who passed away. We would get more but she has become allergic. The lot comes with their 20-gallon long tank and mesh lid, large bag or bedding, timothy hay chews for digestion, food and dust bowls, water bottle, toys and tunnels, 2 s wheels and exercise ball, and travel transport container. Everything is well cared for but in "used" (with the gerbils) condition, but has been washed well. The tank and lid are quite expensive new and the dust bath alone is pricey. All you need with this set-up is the food and the pets!
P.S. Aquarium has very slow leak for fish - works perfect for dry pet set-up.
