Once Solis finished putting his things away and the left over bags in his trunk, all that was left is his satchel and a box on his bed that has the Slytherin symbol on it.  Taking his robe out of the satchel, he put the bag in the wardrobe and the robe over his desk chair before taking the lid of the box off. Inside are clothes with the houses colours or emblem, three ties, a pair of gloves with a matching hat and scarf, a new robe and uniform, and his class schedule.
