Kids Marauder's Map Sequin Reverse T-shirt

This Tee features a flip sequin design, brush to reveal Harry's lightning bolt on a black background or wipe the other way to reveal the iconic phrase 'Mischief Managed' with a pair of footprints below. Surrounding the flip sequin, the text "I solemnly swear that I am up to no good" has been embroidered. Do you solemnly swear that you're up to no good?
