I love that shop! They're so clever, they didn't even need academic grades to make all of that, gosh!
My favourites and not:
None of the Skiving Snack Boxes, since I hate being sick and skipping lessons.
Quills: No need of a Self-spell checking nor a Smart-answer varieties, but it'd be good, if I use quills, to have a Self-inking!
Wonderwitch Products! Right for us, girls! No Love Potions ... interesting, but I'm not mean. I'd love some
Ten-Second Pimple Vanishers, though.
The Shield Products: no need of that if you're a good wizard or witch, I think.
Weasleys' Wildfire Whizbangs!!!! They rock!
The Trick Wands: funny, but for children

They're very clever, though.
U-NO-POO: eewww, no way!
"Just jokes" I like: Reusable Hangman, Edible Dark Marks, Canary Cremes, Headless Hats,
Portable Swamp.
No need of Patented Daydream Charms, since I'm a daydreamer.
Dangerous or useless products: Punching Telescope, Muggle Magic Tricks (depsite they could be interesting for wizards), Joke Cauldrons, Ton-Tongue Toffees,
Extremely useful and great in periculous situations: Peruvian Instant Darkness Powder,
Decoy Detonators, Extendable Ears.
And I'd love to have a Pygmy Puffs! I've always wondered how exatly they look and where do they have a mouth and eyes and all; I've tried a few sketches, but ... I'm curious. And I've always wanted to have a Puffskein, depsite I wouldn't let him eating anybody's snots!
