Review on 🎨 Vibrant Uchida 912-6A 6-Piece Opaque Stix Primary Set: Unleash Your Creativity! by Amy Mcleod

Okay, here's the thing. These pens are a lot of fun. Pens are great for marking your items as they appear on a black background. Folders, notepads, calculators and headphones are easily and clearly marked as your own. "Opaque" ink initially appears as if it is not visible, but gradually becomes lighter. I wouldn't recommend them for drawing. The ink bleeds through the paper and appears darker on paper than on plastic or other objects. Also, sometimes the ink dries up and you have to wait several hours for it to recover. The first time this happened to me I almost threw the pen away thinking it was dead forever. Compare to sharpies. If you need a permanent marker to draw on a black background, order now!
