Simply hang it on the edge of the breeding pot, and it automatically drains rainwater exceeding the set water level and prevents the medallion from escaping.
Compact size (L x W x D): 7.1 x 1.4 inches (180 x 35 mm) for smaller medallion pots.
Reversible core (lead board) sandwiched in black and gray felt.
You can choose the front and back to match the color of the pot and your preference.
