Evelots Cemetery Grave Cone Vase for Fresh/Artificial Flowers-Sturdy Stake-Set/6

Product is described as Patriotic, but picture doesn't show. Are they plain as shown in picture?

What is the diameter under the flange and the diameter of the flange?

length of vase? length of spike?

Does the cone have a hole in the bottom where the stake attaches? I don’t need the stakes but need to make sure that liquid will not seep out.
