I purchased a lot of these last year along with the Parks Waterproof Garden Marker linked with the description of these labels. The T-Stakes Label description says to simply apply a little scouring powder to the permanent marking pen writing to remove the writing and use again. When I bought them I liked the idea that I could use them again. It takes a lot of scouring powder along with scrubbing and muscle power to try and remove existing writing. Even then, the writing does not all get removed. I would not recommend purchasing these unless you want to spend a lot of time trying to clean them.
