When you want to highlight without ruining the flip side of your page (especially on thin paper like planners, journals, or Bibles), the "best" set depends on whether you prefer mild water-based ink or solid gel stick formulas.
Here are the top-rated sets of highlighters known for not bleeding through paper:
The gold standard for journaling and note-taking. They feature a mild water-based ink that is translucent enough not to overwhelm the text and rarely bleeds through standard notebook paper. They are dual-tipped (chisel and fine bullet tip) and come in gorgeous aesthetic/neutral color groupings. You can find them on JetPens.
If you are terrified of liquid ink bleeding through extremely thin paper (like Bible pages), a solid gel stick is foolproof. They glide smoothly like a crayon/pastel, require zero dry time, won't smear pen ink, and literally cannot bleed through paper. You can check options out directly via the 
Mr. Pen Store.
MUJI Highlighters Known for a minimalist aesthetic and a calm, muted color palette. Their water-based ink is formulated to highlight cleanly on notebooks, planners, and study materials without soaking through most common paper types. Available via the Muji Online Store.
Another stellar gel-based option specifically designed for color-coding scripture or thin planner pages. They glide on flat, don't smear adjacent pen ink, and can even be sharpened if you prefer a more precise edge. Browse the collection on the
