These are 4" x 4" wide and 4.5" tall. Great for Venus fly traps if you wish a larger pot, but really perfect for Sarracenia. They are dark green in color with a smooth finish to keep your media from sticking inside during transplanting. The walls are thick, almost crush-proof with drainage holes in the bottom. A rim around the top adds to the strength and ease of handling. We've been using the same pots for years, and not a single one has fallen apart! Just wash, and reuse! Comes in a pack of 10.
