Thanks, Mary Ann. It's surprising that there's nothing like the Kincaid/Paw Paw type of marker in the UK. And I was getting very fed up with labels becoming illegible because the writing faded away.
@sunnyvalley,
@IrisLilli
Sharlene and Lilli, in case you're interested, I bought the markers online from pflanzschild.de at a cost of 189.90 euros for 250 markers (inc VAT and with free shipping).
