Roterunner 8 Multicolor Erasable Gel Pens + 8 FREE Ink Refills 0.7mm Retractable Fine Point Smooth Planner Pens Eraser Pen for Coloring Best Erasable Pens for Kids & Adults (White Casing)

The roller writes smoother, prob because it’s more like a .7. It looks like the cartridge is pretty full compared to all my other erasables. I’ve tried all the ones I’ve found on Amazon. My biggest problem is a significant number of others dry out way before they should. Even when the cartridge is still halfway full. There’s very little you can do besides shaking them like a thermometer or just lightly hit a piece of paper straight up with a scant swipe motion to get them going. I’ve tried dipping them in alcohol, oil, and putting them in hot water to hopefully soften the ink up. Doesn’t work. These write much smoother to begin with. I’m hoping they last longer. I’ll be back if there are any problems. Only started using them but like them much better already. The difference between the 2 blues is negligible. I was anticipating a turquoise as the clip color suggests, but there’s hardly any hue difference. The pink is ok, but could be a scant bit better. The green is very nice. The erasers are tougher, but they do the job without ripping the paper. Thank heaven they don’t waste money on a yellow, which never shows up. More variety on colors would be cool, especially if they could offer bright neon colors. I am disappointed in not getting a turquoise color. The other brand cartridge fits in mine, but can definitely tell right away how much more difficult the flow is.

DO NOT ORDER. Over half of the pens do not write at all. Out of the pack of 8, only 4 actually write. I guess it’s a good thing they come with an extra refill even though 2 of the 8 refills don’t work either.

A few of them don't want to work, even after licking the tip 😉. The ones that work are brilliant! Pretty colors and the eraser is just the "butt" of the pen. I just wish all of them worked.

Write smoothly and erase well. Will be using these in school this fall. Just had a problem with 1 ink not working.

These pens are very poor quality. The ink is not vibrant at all. They do not write smooth. The pens feel cheap in your hand. Several were completely dried out before initial use I am very disappointed.
