Bút Dạ Vĩnh Viễn Màu Trắng ARTISTRO 2 - Bút Đánh Dấu Chống Nước Cho Lốp Xe, Vải, Đá, Thủy Tinh, Gốm Sứ, Gỗ, Giấy - Bút Sơn Dầu - Đầu Siêu Nhỏ 0.7mm

I’ve used it on dark glass jars and a black t-shirt, and the white stays put even after a wash. The ink flows smooth without any clogging, which is rare for a fine tip. Just wish the cap was a bit tighter, but the result is solid.

The 0.7mm tip is perfect for writing fine details on glass jars without any bleeding. It's been through the dishwasher once and the white still hasn't faded at all.

Tried it on a black t-shirt first, and the 0.7mm tip glided over the fabric without any bleed or clogging. Wrote on a glass jar right after and it dried to a sharp, solid white that actually sticks. Exactly what I needed for labeling stuff around the house.
