WonderWitch products are love potions and other products, such as Pygmy Puffs similar to the purple one Ginny got and named him Arnold, for witches. They were created by Fred and George Weasley for their shop, Weasley Wizard Wheezes. Although they were banned with the rest of the Weasley Wizard Wheezes products, they could be sent in disguised as perfume or other such bottled products as a part of the mail order service.
