Avery 標準永久黑色馬克筆 - 12入

I've been using these on plastic storage bins and shipping boxes all week, and the ink hasn't smeared once even after things sat in a hot car. The low-odor part is a real plus since I work in a small room, and the chisel tip switches between bold labels and fine details without any hassle.

The chisel tip gives a nice 3/16” line that works well for labeling cardboard boxes and plastic bins. Ink dries fast enough that I haven’t had any smudging yet, though the black could be a touch darker.

The chisel tip on these markers is great for switching between a fine line and a thicker one, and the ink dries super fast on cardboard. Only took off a star because the black isn’t quite as deep as I’d like on metal surfaces.
