Review on Chalky Crown Metallic Liquid Chalk Markers - Dry Erase Marker Pens - Chalk Markers for Chalkboards, Signs, Windows, Blackboard, Glass - Reversible Tip (8 Pack) - 24 Chalkboard Labels Included - Metallic Colors - 6mm Tip Size by Amy Mcleod

So these markers are great for keeping the color on the tips. It takes 2.5 minutes to shake and press the tip before you can write. I recommend flipping the tip over so you have the end of the bit for two reasons. 1) It saves you time to get the ink into the pen. So it takes a little over a minute. I would do a combination of shaking and squeezing the tip. 2) The round end fills with ink quicker and the chisel end also doesn't chip / have dimples that break the line into your letters. Look at the 2nd phone, there is a line in the blue and purple letter chisel. It also takes about 2.5 minutes for the chalk to dry completely. You will also need a damp cloth to wipe off the chalk. Generally clear bright colors visible from afar. I will update once I have them more than a day :)
