Man, Proware has released way too many anime-related franchise. It would be faster to read their official page directly.
While most items are collector-only i.e. no practical value, this little tool has raised my interest:
These are small magnetic clips featuring anime characters; Hiiragi sisters and Konata/Miyuki from Lucky Star is just one of many examples. Other characters are from The Melancholy of Haruhi Suzumiya, Code Geass, Magical Girl Lyrical Nanoha, School Days, Saiunkoku Monogatari, Ah! My Goddess, Fate/stay night, Full Metal Panic!, etc. These small magnetic clips are perfect for bag sealing e.g. potato chips.
