First in line is a Professor Severous Snape plushie. I think it totally captures his essence perfectly. And its squishy to boot. Although I am not sure if our dear Professor would be amused by this.
Next in line is a Slytherin Crest Silver Bracelet. It can also be converted into a necklace if you prefer that as well. There are quite a few really cool items in this shop so be sure to check the rest of them as well.
And last but certainly not least, a Slytherin Inspired Pendant. It features a snake, a broomstick, and is sparkly. What more do you need? How about a pair of earrings to go with it?
