I absolutely LOVE the Pilot Frixion Erasable Pens so I thought it would be fun to give the Erasable Markers a try. First of all, when any marker claims to be erasable, I can't help but be skeptical. But, these are actually AWESOME! They are available in all types of amazing colors. I ordered the ones above (from top to bottom): blue, pink, soft green, light blue, green, and black...from Jetpens.com.
They write smoothly and erase nicely. All of the colors I purchased show up very well on the Filofax "To Do" list page...although the Soft Green is a little light.
If you hold the page up, you will be able to see the writing on the other side. However, the ink does not bleed through. I highly recommend these markers! They work great in my Filofax and add just the right amount of extra color when needed. I love them!
