Twinkle Club Double Ended Highlighter Clear View Twin-Tip Marker Pen, Chisel and Fine Tips, Assorted Colors, 6-Count

Amazing highlighters for all sorts of papers and pens. I tested with different papers (tomoe river paper, printer paper, bible paper) and it didn’t bleed trough. Also tested with different inks, including: coleto hi-c, several fountain pen inks, micron, jetstream, zebra sarasa and only the colleto smeared a bit on tomoe river paper.I’d recommend this set.

Perfect and doesn't bleed on other pages

Bright colors, but when opened up to use, yellow and pink highlighter we’re leaking all over paper and my hand :(

I love the markers, however, one marker came broken and the other came dried out.
