Flying to you / Transportation of small things

It's inconvenient for someone who needs to go to the high floor just because he forgets something in his office.Its flying theory is the same as parachute. When you need to give someone at the bottom of the building a book and are too lazy to go downstairs, you can just turn to the ‘Fly to you’ for help. What you just need to do is sticking the book to the parachute and throwing it outside the window. Then the small parachute will open and finally make a slow land with the book on it.
We also design the ‘parachute box’ to keep them. Double over the parachute and it will suit this ‘parachute box’. A small parachute box can store more than 50.
