I bought these years ago (2009)

Only problem is that if it's not embossed really clearly/hard, you can't read it later on as the aluminum just mangles. Mulch & aluminum tags don't go together very well due to the mulch squishing the aluminum into illegibility. And it's not very prudent for me to attach the tags up high because then I have to remove them from my roses when I prune them in the spring. So they didn't work well for me unfortunately.
