That extra-fine 0.7mm tip is perfect for getting clean lines on my fabric projects without bleeding, and the ink hasn’t cracked or faded after a few washes. I’ve also used it on rocks and glass for a craft session — it flows on smooth and stays put. Definitely my go-to marker now.

The 0.7mm tip is perfect for writing on my tires without any blobs, and the paint sticks so well even after driving through rain. I've used it on a glass jar too, and it hasn't chipped after a week of washing.

I was bracing for smearing when I used it on a ceramic mug, but the oil-based ink set almost instantly and hasn't budged after two dishwasher cycles. The tip is precise enough for tiny lettering, and the flow stayed consistent the whole time without any clogging.
