Mash’ems are small collectibles that can be squeezed and thrown around. They come in blind boxes so you’ll never know which character is inside. Personalty, My favorite is the Batman and Disney collection. Tech4Kids sent over 6 blind boxes for me to review but lets be honest, These are not just for kids. I was super happy when I saw that joker was inside one of the boxes. Any comic book or toy collector will enjoy opening up one of these mystery boxes.
