Ecopots 11.8" x 11.8" x 10.3" Round Dark Gray Plastic Flower Pot with Durable Feature

This is a lovely pot but it has a huge problem. I bought it for a plant that is potted in 11inuch round pot that is 9 inches high. It should have fit this planter perfectly, but it doesn't. On the inside wall of this planter are 4 ridges sticking out about 3/4 inch from the sides starting at the bottom interior and ending about 3 inches above the bottom. So my plant container hits those ridges and doesn't drop all the way to the bottom of the planter. I really wish that the seller would have shown a photo of the interior of this planter so that one realizes that it does not hold as large a plant container as one would expect from the measurements given.
