We recommend a pot that is 1 - 2 cm bigger than the size of the plant pot your plant is currently in. These are pot covers and do not have drainage holes so are not suitable for direct planting.
The larger pot opening has a diameter of 9cm and fits out plants with 7-8 cm pots (such as our smaller Tradescantia) and the smaller pot opening has a diameter of 6 cm, perfect for our baby plants with 5.5cm pots.
Nothing actually wrong with the pot but it would have been perfect if there were draining holes on the bottom
I love there quirky pot's!
