Best marker on the market. 6" aluminum triangle that, when paired with a Brother ptouch printer allows you to print elegant labels on your computer. So far, they have lasted and been fully legible for several years in a Zone 4 northeast garden. The only issue I have is that they are Canadian and don't usually deliver to the States, so I buy through Blossom Hill Nursery in Canada that is set up for international shipping. I've been gardening for 30 years and have tried just about everything else and this is tops. Hard to damage and reusable. Can write or print on both sides. Oakes Daylily markers are excellent too, but they are a bit pricey.
