Interesting rainbow color pens in nice hue combinations. Some seem to show the variations better than others but overall a fun addition to use on coloring books!

The gift recipient was very pleased with them.

The pink and yellow hardly shows on white paper. It should have more pink in it I think. The green were too light as well. Couldn’t hardly see what I wrote. The other colors are good though

Very nice, would buy again.

The media could not be loaded.  I bought these swirled ink (marbled ink) pens, thinking that as the color would be constantly changing/revolving between the 3-4 ink colors in each pen... But instead what you get is all the.colors mixing together to make just one mixed up color... And out of the 10 pens I received, the pen colors only resultes into 3 total colors. Greens, purples, amd an orangish color (pinks and yellows mixed together.On top of all that, they don't even write that smooth, nor are they even that vibrant. In fact, with the exception of one of the purples & greens, they write rather sheer and the ink is hard to see, even on stark white paper. (Pictures provided)But hey.... they're pretty in appearance tho. ¯\_(ツ)_/¯

When pressing lightly and especially at a slight angle, it doesn't write reliably. Other ball point / gel pens write much more smoothly.Also the color change is pretty slow, not at all like the product image where even a short loop is nicely marbled. I can scribble all across a page three times and see no appreciable change in color. I was hoping for a slight change in a line of writing or so.

To be fair, these are not exactly like the fabled Zebra Super Marble gel pen of old. Rather than drawing in all colors, each pen is themed around color mixes. But the effect is the same in practice. If you really want it to look like Super Marble, just alternate pens while you write or draw.Make sure to keep the caps on or the gel will dry out and become hard to use.

Good gel, easy to color with.
