im pretty sure if this is done.
this present box at first world bank located at overvault which can be gained access by completing overdrill make sure be fast. or present box will dissapear
photo form generalmcbadass's video difficulty:almost impossible

Hardest Present location. you need must jump of from fire exit at 3rd floor. and interact it. its abit hard. but the steel beam is non solid. make sure any friend will come and revive you.photo taken form obeze ducc's 9 xmas present box location video
difficulty:Very hard

who did this. but anyone if do that. i will clapping it. to do this. you need jump off top of one scallfolding to an top of street light. its abit hard. but find an way to climb it Difficulty:Hard

There's 25% chance to an green top container which was at entry of industrial park will appear and its open. you have to climb off there and there's your present box Difficulty:Medium

Abit confusing. Credits to DoruntuZ for his guide
his guide said that
"The Christmas present is behind a box in a container right before the escape zone."
this is mains right before the escape zone. its in trap container have box its behind of box. but again im not sure about that Diffculty: Medium

annoying one. before another door open at sewers(final escape part) make sure check any door.
Before opening another sewer door. its on first closed section. its on the carboard boxes.requies luck. due to you need use first exit of sewer. not second or third one Difficulty: Normal

this present box is located at behind of ventilation shaft. its not annoying. its abit easy to do. this ventilation shaft located at near to escape Difficulty:Easy

There's an chance you will have to escape form basement area. and if you using this escape before finishing heist. go to other elevator shaft. its abit dark. but you will see your present box Difficulty:Easy

i place it in last. because is too easy.
if server room door is open come to there. go to an corner. you will see. present box is hidden. Difficulty: Very easy
