Hi, I want to find out the bottom dimensions of this storage box (https://jiji.sg/storage-boxes-baskets-containers/10693-622014-satra-storage-box.html#/4748-color-translucent/5002-size-large_60l) Also, is this an air-tight box?
Good day, the specific dimension of the box is seen in the last picture of the product. There is a rubber padding that allows it to be air tight. Thank you
