I like the Startostar garden markers, because.
1. They are sturdier than other ones I have tried, and
2. They can accommodate the one-inch (.94") wide tape of the particular Brother labelmaker that I have. It's model PT-D610BT. I chose this model because it can print two lines of print without the print being too tiny for me to read.
3. These markers can be ordered in black. I find the black to be less obtrusive in the garden landscape. But if you order label tape that can give white print on black, ihe markers are still nicely unobtusive, while still being easily readable.
Although the label portion is powder-coated galvanized steel, the legs appear to be stainless steel, and they are supposed to be rust-proof.
It has taken many years for me to hit upon this combo, and I really like it.
