I have used the P-Touch labels for years. In fact there's one I just brought in that was one of those roundish labels with the long stem on them, and they will usually get broken off by the elk or deer or hubby for that matter, but this one is in tact. As I turn it over to see the date on the back that tells me when I first put it out, it says Aug 1997! The labels themselves that I use now days are the metal mini blinds, they make great ones IF you make them long enough., I would suggest 8" so they stay in the ground when the freeze and thaw happens. We live in Zone 5a.
