Houston-based manufacturer TuffyPacks recently unveiled a line of bulletproof backpacks aimed at children and young students, featuring their favorite characters from movies and TV on the packs. These new "Ballistic Shield" packs were supposed to roll out as Back to School shopping gets underway around the country, but sales spiked over the weekend in the wake of the mass shootings in El Paso, Texas and Dayton, Ohio. The new line includes bags featuring Marvel's Avengers and Disney Princesses but there seems to be one major problem: The Walt Disney Company never signed off on the use of the characters. According to The Hollywood Reporter, Disney is aiming to shut down the sales of these new TuffyPacks items that feature its popular characters. "None of these products were authorized by Disney, and we are demanding that those behind this stop using our characters or our other intellectual property to promote sales of their merchandise," said a spokesperson for Disney.
