The Search for the perfect plant tag continues: Slate tags??

[peeweelovesbooks]

Hi guys.

For some reason, the tags that I buy (which are 6 x 1) and are printed on both sides) become brittle quite fast. I've been looking for some tags that are 1) durable, 2) attractive and 3) not too costly.


So, in going through the listing on Etsy.com, I came across this listing for tags made out of old slate roofs:

What do you all think? Is slate inert enough not to damage my plants? I plan to print a transparent label with black lettering so that it will blend better.

Your comments/opinion is welcome.
