Ollivanders Bespoke Wand Selector
In response to overwhelming demand, Mr Ollivander, world-famous wandmaker, has created a means of wand allocation (or, more accurately, wizard selection) involving nothing more than thirteen simple questions.
Certain combinations of wand and core are more unusual than others, but you can rest assured that if you have given truthful responses to Mr Ollivander's carefully constructed questionnaire, you and your selected wand will enjoy a long and fruitful association. Take a sip of Felix Felicis and try fetching your ideal wand.
