This set of 25 light green, plastic Plant Markers with Pencil makes for easy identification of pots or rows. The black wax pencil that is included makes plant names clearly visible, and the writing will not wash off in the rain or under a sprinkler. The writing can be removed by scrubbing, though, so the tags are fully reusable and will play a key role in your garden for years. We liked the extra space for writing - there is room to include planting date and other key information. The markers are 13cm (5") long with a 4cm (1.5") writing area at the top.
