These dot markers from Koogel are an exceptional value. I have been looking around for a set that contained more than just 4 or 6 colors as most that I could find did. This set has 8 colors. The colors have exceptionally good pigment and the colors are bright. The ink is washable so no worries if the kids accidently get it on their clothes or surfaces. The markers are easy to hold and easy to use. Simply press down a couple times to get the sponge saturated and then you can use the marker. These are not just for making dots. With practice, the kids can make all kinds of cool pictures. This set also comes with a set of 12 plastic stencils with different designs to create. The stencils can be wiped clean with a damp paper towel. We used these markers on cardstock, regular drawing paper, and inexpensive stretched canvas and it worked well on all of it. We bought these to use during homeschooling to practice counting in ten frames, math activities and art projects. My daughter had no problem using them. Even adults can have fun with these. This set is already a great value but right now, you can also get them with a clip able coupon to save an extra 5% off of the regular price. I am overly impressed by these dot markers.
