Draco Malfoy's wand

The wand of Draco Malfoy is 10" precisely, Hawthorn wood and with a unicorn hair core. It was described by Mr. Ollivander as "reasonably pliant". It was taken from him by Harry Potter in Malfoy Manor in 1998, which would have unforeseen and enormous consequences in Harry's final duel with Lord Voldemort.

History
Draco presumably received his wand from Mr. Ollivander in 1991, just prior to his first year at Hogwarts School of Witchcraft and Wizardry.

In 1997, Draco cornered Albus Dumbledore atop the Astronomy Tower, disarming the Headmaster. He was under orders from Lord Voldemort to kill Dumbledore, and had made multiple attempts over the course of the year to do so, terrified for his family's safety. Draco had no idea that by disarming Dumbledore, he became the master of his wand — the Elder Wand, one of the Deathly Hallows. He was unable and unwilling to go through with the murder, and Severus Snape stepped in to kill Dumbledore in accordance with their secret plan.

In spring of the following year, Draco was home for the Easter holidays when a group of Snatchers led by Fenrir Greyback caught Harry Potter, Hermione Granger, and Ron Weasley, and brought the three of them and their other prisoners to the Malfoy Manor. In the skirmish that ensued, Draco was disarmed by Harry, who won the wand's allegiance and subsequently used it. Draco's mother gave him her wand to use.

Carried by Harry Potter
In the aftermath of the Escape from Malfor Manor, Harry Potter had this wand examined by Garrick Ollivander who concluded that it was highly likely that its allegiance had transferred to him. The wand was carried by Harry for the remainder of the Second Wizarding War; seeing action in the Break-in at Gringotts as well as during the final climactic Battle of Hogwarts. Harry appeared to have developed a stronger rapport with this wand than with the substitutes he had used saying that "he was surprised but pleased to dicover that it worked for him at least as well as Hermione's had done".

During the Battle of Hogwarts, Voldemort found that the Elder Wand, otherwise known as the Deathstick or Wand of Destiny, which he had taken from Dumbledore's tomb, was not working as impressively as he had hoped. Believing that this was because Snape had its allegiance after killing Dumbledore, Voldemort had Nagini kill Snape. When he and Harry faced off shortly afterwards, Harry corrected him: since Draco had disarmed Dumbledore, he was the true master of the Elder Wand, not Snape. When Harry disarmed Draco in Malfoy Manor, the Elder Wand's allegiance shifted to him. Thus, when Voldemort tried to use the Killing Curse on Harry, the Elder Wand refused to attack him. The curse backfired, defeating the Dark Lord once and for all.

It is unknown if Draco ever got his original wand back. If so, it is unknown if the returned wand would continue to function for him as it had before Harry won it, as it is never stated how a wand that has been won behaves towards its original master afterwards, or whether the witch or wizard who has won its allegiance can grant it back. However one could argue that Draco was very attached to his wand as he demanded it back from Harry inspite of his possessing what he deemed a "powerful" wand.

Behind the scenes

 * In Harry Potter and the Philosopher's Stone, Draco comments that his mother was "up the street looking at wands", when talking to Harry Potter in Madam Malkin's. This suggests the possibility that his wand was purchased for Draco by his mother, Narcissa Malfoy, and that it therefore never "chose him". However, it is much more likely Narcissa was simply comparing the wandmakers' craftsmanship and that Draco joined her afterwards and was chosen by his wand, when she had decided from which wand shop they would make their purchase.
 * Draco's wand wood matches his date of birth in the Celtic tree calendar. However, it is unlikely that this was intentional on J. K. Rowling's part, as she once commented: "I have only used the Celtic assignations for Ron and Hermione... I liked having a hidden connection between Harry, Ron and Hermione’s wands that only I knew about". 
 * Draco's wand (aside from having his mother's wand) is one of the few wands in the film adaptations to have the same design throughout all eight films. But, the prop in the last two films is all-black rather than brown with black handle.
 * In Harry Potter and the Deathly Hallows: Part 2, Harry snaps the Elder Wand rather than repairing his original wand. It is unknown if he kept this wand in its place.
 * In Part 2 of the final film, rather than saying "reasonably springy", Garrick Ollivander describes it as "reasonably pliant".
 * Hawthorn wands are said to be "most at home" with a wizard passing through a period of turmoil. During the last couple of years of owning this wand, Draco Malfoy was under enormous pressure to murder Albus Dumbledore, and immediately afterwards suffered through Voldemort occupying his family's home. Harry Potter claimed mastery of this wand at a time of great turmoil as well, undergoing a robbery of Gringotts Bank and the Battle of Hogwarts within a short time of gaining this wand.
