This is a stock photo of base ten blocks. At Pic Depot, our objective is to provide you with stock photos to enhance your products, blogs, classrooms and anything else you can imagine. All of our stock photos are taken by us, so they may be used for personal, educational, and commercial enhancements in your products. They, however, are not intended for redistribution. Our stock photos are set at a 300 dpi or higher resolution. Add your own text, photos and clipart to make your projects stand out. The picture will not have the PIC Depot banner on it.
