I've used everything a couple of times, just a little. Only the pink highlighter is new and unused. Pink highlighter → Zebra Fluorescent OPTEX 2 EZ (says "Thank you for donating blood") Set of 3 highlighters → Pilot Ink Refillable Single Thick Spotlighter Water-based OA compatible 4 fluorescent brush pens → Kuretake Brush HiLite If you don't need the case for the Muji color pens, I'll lower the price to 390 yen. Please comment. Please be sure to read the profile before purchasing (^-^)
