This seed planter tool makes planting seeds a breeze! Put away your pencil and make perfect holes every time. This tool features lines every 10mm, for up to 50mm depth measurement. This is handy for seeds with certain depth recommendations. Remember: an inch is about 2.5cm, so each line represents 0.4 inches.
