This is a set of 2 replacement inserts for the Sustee 'Aquameter' Watering Guide.
Easy to replace core refills, just twist off cap - remove used core - insert new core and replace cap.
Core displays blue colour when the plant has enough water and fades to white when it is time to water.
Replace core every 6-9 months for best results.

Sustee refills should be a good product
The Sustee meter itself is great
