I'm trying something new! This is a lovely piece of cork bark to which I have permanently mounted three knobby and two pink sea urchin shells. Inside each shell lives a tiny air plant, which can be removed for watering and care. Plus, you can change the arrangements of the plants to suit your space or mood. You will receive five different and adorable air plants to create a one of a kind faux seascape! The knobby little shells reminded me of barnacles growing along the bottom of ships, or on pieces of ancient driftwood. Virgin cork bark is a lightweight, sustainable, renewable, and environmentally friendly natural resource. Cork bark is “stripped” off the cork oak trees at appropriate intervals without damage to the trees and allows new bark to grow in its place so there is no harm to nature; no trees are cut or destroyed. Simply dunk the plant in water 1-2 times per week and allow to air dry on a towel before returning them to their nautical home. This is a great piece for your desk, coffee table or book shelf. Cork bark measures approximately 5" by 5". Unpackaging and care instructions will be provided. Shipping charge includes a 72 hour shipping warmer pack to help protect plants from cold weather when necessary. This lovely piece of living art will ship USPS priority with delivery confirmation.
