I love that they have extra marker tips to switch out in case the old used tips hardens because the ink dries on to the tip

I have a glass bulletin board in my office, and these pens are extremely easy to write with, and the colors are both vibrant and amazing!😍just be sure to follow the instructions included with these pens

I love this product!!!it’s way better than dry erase pens and it doesn’t have that toxic smell when using it
