This pot has a nice round shape. I poured the Hsin Matte Black glaze over the pot and then dipped the pot in Rutile for a little magic. :)
This pot will fit your 4" plant. It is larger than the 3" pot, and you will probably want to transplant your pot into this planter. I leave the inside of my pots unglazed because the roots like the texture of the raw clay. There is a drainage hole and saucer.
If you would like your items shipped, let me know and I'll look up the cost of shipping and add that to the listing.
I am a potter in San Jose. Please let me know if you have any questions!
