Our dwarf hamster passed almost a year ago and we are no longer planning on getting another hamster. Here is everything that we bought for him:
2 different sized silent exercise wheels
1 vertical exercise wheel
2 houses
half a bag of food
1 sand bath with almost full container of sand
exercise ball
small cage (ok for travel)

We kept our hamster in a much larger cage but this is the one we originally bought at PetCo. I would only recommend these items for a dwarf hamster, gerbil, or mouse, since a larger Syrian hamster will not fit in anything.
