Ink ran out quickly, and the highlighters are extremely light. I do love the eraser function of them. Saved me from a lot of frustration. However, the ink was gone from two pens within 3 days.

Perfect for crafting….Especially if you need to draw lines that you want to “disappear” later. When heat (such as a hair dryer) is applied the ink disappears.

I love these pens. I use them for a variety of things. My favorite thing to do with them is to draw on fabric an embroidery pattern. Iron the back of the piece and the ink disappears! It’s also great for secret treasure maps with grandkids.

Great color selection—lime green not bold enough perhaps a darker green. Haven’t tried the highlighter. Love this for to do lists, shopping lists, planner and or calendar

I bought these originally for my wife to use for crossword puzzles and loved them. Then, I found out they are what the Rocketbook uses for the reusable notebook. (It is a paper notebook Sam's sold that erases with water, but that's because of special paper. On regular paper, this ink erases with rubbing the eraser.) That was amazing. Since then, I pretty much use these pens for everything because I hate crossing out mistakes. But there is an interesting bonus that I've discovered. Another way this ink disappears besides the friction of rubbing with the eraser is that high heat will make the ink disappear. But to get it to come back, you just need to subject it to cold. Well, imagine the fun that could be. I taught my grandson that he could be magic when I sent him a postcard with just a blank smiley face done in permanent marker. But I colored the picture with these Frixion pens, then took a hair dryer to it to make the colors disappear. I told him "Put this card in the freezer for 10 minutes." Now he is pretending to be magic. :)

Our family loves this product. I still use a paper day planner and the erasable ink allows me to color-code events without committing to permanent ink. The highlighters are perfect for kids' books, scripts, and notes. They erase easily without leaving behind any debris, as is the case with pencils. These are very handy.

These pens are terrible. I have a job and do not do an extreme amount. Writing and each pen has lasted me less than one day.

I am happy with this set. The pens write smoothly. I will say the orange and green are light in color. Highlighters are bright. I like the colors available. I use these for my bible study.

Nice pens although I don’t feel like the ink flows as freely as regular Pilot pens. Love the rainbow of colors and the fact they erase but they do feel rougher to write with.

These are the best pens for high school students and middle schoolers. They erase cleanily and are perfect for any student. Having highlighters is a bonus. I bought them on sale and you can't beat the price. FriXion pens aren't cheap, but they are worth it.
