AAkron Color Changing Mood Pencil with Eraser - Graphite Pencil - Made of quality wood, Set of 24, Assorted Colors - MADE IN USA

These color change fairly easily and are pretty good contrast. Only the blue and red ones aren't super; the blue turns into teal and the red turns into a sort of orangey color. Purple turns to pink, green has yellow, orange turns yellow, red turns orange, blue turns sort of a lighter teal. If they don't seem super-high contrast initially, we found that putting them in the fridge for 3-5 min seems to ensure all of the pencils reset back to their "normal" color. Warm hands work best, but if your hands are a bit cold, rubbing the pencil also works due to friction. Pretty good!

I love these pencils. I bought them for school for the kids to use. They really work, the color changes. In fact, I keep having to repeatedly buy them for two reasons: they get used up pretty quickly, and they get stolen. They're really cool!

I was surprised to see that all of the erasers are actually black when in all of the pictures and description it says and shows that they match the color of the pencil. It isn't a game changer for me bc the colors do change ok the actual pencil itself and that's really all I was banking on. Still super cool minus that one discrepancy!

This product is a great value for the money, made of great quality, durable, easy to sharpen and easy erasability, comfortable grip and the color-changing effect is super cool and unique! My daughter kept putting it in front of our portable heater to get the colors to change. I wish I would of taken a video/photos, but she took these into school to give one to each student in her class room. I will for sure be purchasing this product again in the near future though! I highly recommend this product also!

Pretty neat pencils. Need warm hands to get the color to change. The lead seems to be a good quality.

Most of the colors changed to something different enough from the original that it was fascinating and fun to see the change. A couple of the color differences were slight so they were a bit disappointing. It takes quite warm hands to effect the change and it does not linger as I thought it would. The kids. . . love 'em!

it definitely changes color

Waste of money. Only the blue changes and it’s not that much. Buy another brand. $15 is a rip off.

They work as described.

Every year I order these pencils as a gift for my students. I was supposed to receive a packet of 24 pencils, but the bag was broken and only received 20 pencils.
