I needed self-watering planter inserts for my decorative metal pots and I was having a tough time finding the planters that fit those pots sized 4.5 and 5.5 so I bought these 4.3 and 5.3 size platers and they fit perfectly. It would be great if it had a water level indicator design but I guess for such small size, it's difficult to do that. Overall, I am happy with my purchase.
