Small pencil sharpeners are normally made out of plastic but not these! These are made out of untreated wood and metal. We all know how easy it is to loose a pencil sharpener- especially if you are sending it to school with kids! By having a wooden pencil sharpener you aren't loosing potential microplastics when it falls out of your pocket. Made the switch today! Pairs well with Recycled Colored Pencils.
