The machine includes a tamper (see pictures. Hangs on the top left with a magnet), a milk jug, four sieve inserts for the plunger, a water filter, cleaning tablets with cleaning utensils and tools.
To make a cappuccino, for example, all you need is a coffee grinder, a cup and the ingredients. I also recommend a tapping bowl for the coffee grounds. I have the following and am completely satisfied:
Sage the Knock Box Mini (1 pc.)

I can confirm Jonas' comment. I am very satisfied with this machine!
