Power Pen Learning Cards Addition Subtraction Time Money 4-Pack Plus Pen

Power Pen Learning Cards Addition Subtraction Time Money 4-Pack Plus Pen Set of 4 learning cards packs. Hand counted and complete. Only the subtraction deck is missing the solutions card, but the answers should be obvious. I'm also including the pen, but it DOES NOT WORK. I do not know how to fix it, but maybe you can. Listing is for 4 packs of cards and the pen together. Sold as is.
