Started years ago with the rectangular foam blenders, then moved on to the small foam circles, then the domed foam - all in an effort to get a smooth ink blend. These are BY FAR the best tool Iβve found. I resisted the long handled brushes because everyone chokes up to the head - I was waiting for a brush with the handle on top. I liked that these include a cap. They put down a lot of ink very quickly. Love them!
