I’ve been using the USArt Supply Jewelescent 100 GelPen set for a little over a week now and love them! They are vibrant and color and write smoothly and beautifully. There are many colors and shades to choose from which makes it fun for coloring and other projects. They are comfortable in your hand as well. The box they come in is a nice storage unit as you use them. My only complaint is that they seem to go through ink rather quickly. I am a little concerned that they may run out with frequent coloring projects. They are available for purchase on Amazon.US Art Supply Jewelescent 100 Gel Pen Set I did receive this product free in exchange for my honest review and opinion. #usartsupply #gotitfree #gelpens
