What is ホワイトボードマーカー（消し付、細芯、黒、３本）?
Let's get straight to it: three erasable whiteboard markers in a single pack for ¥110 (about $0.70). That's not a typo. Daiso's Fine-Tip Black Whiteboard Markers with Eraser are one of those products that make you do a double-take in the stationery aisle.
Each marker measures 13.8 cm × 2.5 cm × 1.5 cm — compact enough to slip into a pencil case, substantial enough to grip comfortably. The body is made from polypropylene, and the fine tip uses a polyester fiber nib loaded with oil-based ink, delivering clean, consistent lines approximately 2.0 mm wide. That fine point hits a sweet spot: precise enough for detailed notes, bold enough to read across a room.
Here's the standout feature: a built-in eraser cap at the tail end — write and wipe in one motion, no hunting for a separate eraser. Even smarter? A small magnet is embedded in the tip cap, so the marker snaps right onto any magnetic whiteboard. No more "where did the marker go?" moments mid-presentation. Manufactured in Korea and sold in a pack of three, this is a genuinely thoughtful design at a price that feels almost unreasonably generous.

How to Use It — Hack Ideas
Primary Use: Clip the set to your home or office whiteboard, use the fine tip for legible to-do lists, meeting notes, or teaching materials, and erase instantly with the built-in cap eraser. The magnetic tip keeps markers docked right on the board — always within reach.
Hack #1 — Fridge Planning Board: Stick a small magnetic whiteboard sheet (also available at Daiso) to your refrigerator. Park these markers directly on it using the built-in magnet. Now you have an always-ready grocery list and meal planner that the whole family can update — zero paper waste, zero lost pens.
Hack #2 — Temporary Label Maker for Clear Containers: Writing on glass or smooth plastic surfaces? These oil-based ink markers write cleanly on mason jars, storage containers, and even mirrors. Use them as temporary labels for pantry organization — rearrange your storage, wipe, and relabel without any residue. Great for seasonal reorganization or labeling meal-prep containers for the week.
Hack #3 — Kids' Art Supply: Pair with a Daiso mini whiteboard and let kids practice writing, drawing, or math problems. The built-in eraser makes it mistake-friendly, and the fine tip encourages neater handwriting than chunkier alternatives.
Reviews & Verdict
Among the full lineup of Daiso whiteboard markers — spanning thin to ultra-thick tips, single colors to multi-packs — this fine-tip black three-pack consistently draws attention for sheer value density. Reviewers highlight the magnetic feature as a genuine quality-of-life upgrade, noting it solves the universal "missing marker" problem without any extra accessories.
The fine tip earns praise for producing clean ~2.0 mm lines that are easy to read on standard whiteboards. Users testing the eraser cap report it works well on smooth whiteboard surfaces, though — as with most whiteboard markers — performance may vary on older or low-quality boards where ink can ghost over time.
A common caveat: the oil-based ink means be careful on porous surfaces — it's not designed for paper or fabric. Stick to non-porous boards, glass, and smooth plastics for best results. Also worth noting: the pack is black only, so color-coding enthusiasts will want to grab one of Daiso's multi-color sets alongside this one.
Overall sentiment is overwhelmingly positive. For households, small offices, classrooms, or anyone building out a budget-friendly home organization system, this pack delivers functionality that easily rivals products costing three to four times as much.
Value Score: 88/100
Three markers, a built-in eraser, and a magnetic clip feature at ¥110 is genuinely hard to beat — solid price-to-quality with strong hack potential across home, office, and classroom settings. A point or two off only because the single-color limitation and oil-based ink restrictions narrow its versatility slightly. Great value, worth every yen.
