ARTISTRO 2 黑色與白色永久性記號筆 - 防水記號筆適用於輪胎、布料、岩石、玻璃、陶瓷、木材、紙張 - 油性油漆筆 - 極細筆尖 0.7mm

I've used these on ceramic mugs and glass jars, and the oil-based ink stays put through washing without flooding or jamming. The extra-fine 0.7mm tip is perfect for clean, controlled lines.

The 0.7mm tip glides over rough tire rubber without skipping, which surprised me since most pens clog up after the first pass. Ink dries solid and hasn't cracked or faded even after a few washes on the fabric I tested.

I’ve used these on glass jars and a ceramic mug, and the black paint hasn’t chipped even after a run through the dishwasher. The flow is consistent, no blobs or skips, and the extra-fine tip gives crisp lines every time. Took a bit to shake and prime, but once it’s going, it’s a joy to work with.
