Erasable Gel Pen Set – Blue 0.5mm Thermo Ink Pens for Study, Practice Writing
This erasable gel pen uses special blue ink that disappears automatically over time. With no need to erase manually, it's ideal for reusing worksheets or study materials. The thermo ink reacts to paper and temperature, causing the writing to vanish completely within 30 minutes to 5 hours depending on the paper type.
The set includes one pen body and 10 refill cartridges, making it economical for frequent use. Great for memorizing vocabulary, repetitive review, and effective study sessions.
