The DIY mug and crayons kit is a great little set to have around for kids to personalize their own cup in a creative way. You will get an 8 oz plastic cup with an outer paper lining for them to draw on. It will also come with a box of crayons with four colors, green, yellow, blue and red. Since children will be using paper to decorate though, you can use whatever crafts you have around the house or want to pick up. You can even switch out the paper for when they have some new ideas to get out. These are great as an activity at a party for the guests to do or for your children to do at the house to have they're own custom mug.
