1 x Cheerson CX-10 Mini RC Quadcopter
1 x 2.4G transmitter (needs 2x aa batteries)
1 x USB charging cable
1 x Set of spare blades
Not sure if this comes retail packed or in a plain white box these days I think it will be the white box which is probably a good thing as the retail boxes had a habbit of arriving rather squished I found.
And if you want something with a bit more flight time and built in prop guards the Eachine H7 that banggood also have will fly for about 6 minutes compared to 4:30 for the cx-10 and is $17.99
Be aware hat the pcb tracks for the motors break easily. I know because I have 2 and I have had to repair them both.
