Harry Potter fans can demonstrate Slytherin house pride with this LEGO brick-built house banner (76410). An ace everyday gift for kids aged 9 and up, it features a printed tile with the Slytherin crest and a hanger to display it on the wall. The banner also opens to reveal a spellbinding recreation of the Slytherin common room with a buildable sofa, lamps and steps. A slide-in lenticular backboard creates magical 3D effects, including moving monstrous eyes, a light turning on and off, a secret message appearing in the cupboard, and more.
