Many different designs and the best part...THE BOX! While that may sound stupid, for me, a Potter nerd and collector, it was the box I wanted. No where else can you get a wand in an Ollivander's box, complete with dust.
The Nobel wands on the WB site are all character wands, meaning the wand design used in the films, whereas the ones at WWoHP are what some have started calling "birthday wands", meaning the wands can be selected to match the wizard based on birthdate. There are many different types and styles.
