The Spells Collection seems to be one of the more popular collection as many of the shades were sold out by the time I had ordered. This is partly the reason why I don't have as many shades from this collection. However there are still some of these beautiful shades available for sale right now.
Riddikulus - Pinky purple with holographic and pink sparkles. Reminds me of My Little Ponies...xD
Impervius - Metallic silvery grey
Serpensortia - Golden olive with purple sparkle
Rictusempra - Rust orange-y brown with iridescent and orange sparkle
Diffindo - Dusty aqua with gold and holographic sparkle
*EDIT 9/19/11* I was lucky enough to be able to purchase Miss K's last jar of Wingardium Leviosa when she discovered a few stragglers! Swatch is below.
