I made these last year and they were a huge success so I decided to make them again. I used a sharpie marker to make the faces. The clementines do have a wax coating and that can cause issues with the marker. You can wash them really well or just have more than one pen to use. They are perfect for schools that don’t allow sugary treats or homemade treats. They are healthy and home decorated not homemade. I added them to treat bags along with pencils, erasers, bat rings, and stretchy mice.
