Water-refillable syringe for tubes

Description

Special syringe allowing the refilling of Fourmiculture tubes with water using a special needle adapted to the diameter of the refilling hole.

After refilling, ensure the tube is completely dry, then seal the hole with Scotch crystal tape (use only this high-quality brand to prevent leaks). Open the tape once a month to allow air to circulate, or leave the hole open in areas of high humidity.
