Harry Potter Card - Magical Water Plants of the Mediterranean

Out of stock


A Herbology textbook written by Hadrian Wittle, Magical Water Plants of the Mediterranean, was used by Neville Longbottom in Harry Potter and the Goblet of Fire, in which he discovers a way for Harry Potter to breathe underwater for the Lake Trial in the Triwizard Tournament, a magical plant named Gillyweed that transforms the consumer into a human/merman hybrid, with webbed feet and hands, and gills, which allows Harry to complete his task! This greetings card, designed by the graphic design team, Minalima, mimics the front cover of the book, with detailed typographic designs, and silver printed detailing. Perfect for any Herbology enthusiast!

Measurements: 13cm (width) x 17cm (length).Blank inside, with a white envelope.

To see the rest of our Harry Potter greetings cards, visit the Social Stationery section of The Shop That Must Not Be Named website which specialises in official Harry Potter merchandise and gifts.
