These eight Pilot Frixion pens cost me £11.50 including postage from Ebay. I have been using Pilot Frixions in black as my pen of choice for all my planners. With these pens I can rub out my writing if necessary without making my pages looking a mess. My black pens came from B&M Bargains with 2 for £3.99, I think so these colours are way cheaper and they come all the way from Japan. I shall enjoy using them.
