Here's the breakdown. I think the worst part of these sets is that they aren't even display worthy. I could forgive the poor paper choices if there weren't the TMs and copyrights all over the pieces. They really feel slapped together.
Ron's box:
Gryffindor Uniform Stitched Crest - TM on the Gryffindor name. HUGE WBE copyright patch sewn onto the back.
Quidditch World Cup Map - Nice paper on this piece. TM by the word Quidditch that's not terribly subtle.
Howler Letter - Incorrect envelope. Light paper stock. TM on Ronald Weasley, Hogwarts and Gryffindor. The WBE copyright is HUGE on the Howler letter.
Dumbledore Card - TM by Dumbledore's name (small). Card is on light cardstock.
Chudley Cannons Poster - rolled and tied with a ribbon. 11x17 and printed like a normal movie poster
Weasley Betting Slip - Very light newsprint-like paper, but it feels accurate. Very tiny WBE copyrigh (hardly noticable). Easily the best done pieces in the lot, but completely esoteric.
Weasley Twins Product package - I don't even know what this is. It's a piece of thick white cardboard with the screaming yo-yo box info. It's not die-cut or anything. I don't know if mine is defective or not.
Hermione's Box:
Love Potion Bottle - Cute box. The replica is not accurate (they've added a base and the tassle is wrong. They also detailed the text with gold paint).
Yule Ball Snowflake Ornament - Metal with an etched TM next to Hogwarts.
School Timetable - Light pseudo-graph paper (digital printing). I don't remember this in the films, and my 11-year-old niece has made better paper props.
Owl Exam paper - Light stock, two sheets. Just a long sheet and a short sheet, nothing that folds out like the real deal.
Yule Ball Poster - 11x17" typical poster
Gilderoy Lockhart Signed Photo - 3"x 4" TMs by Gilderoy and Hermione's names.
Hogwarts Express Ticket - Not gold foiled, printed in yellow (the paper is gloss-coated so it feels very modern).
