Kerosene test tube vase with bark inclusion. Straight sides. Anyone that follows me on instagram will know how much I adore plants with wood (it's such a symbiotic relationship) but without a vessel to hold the water, it won't work. The current model of vases incorporate a half circle with a hole to accommodate the test tube. From beginning to end, I have measured, drilled, cut, sanded and applied a couple of coats of lacquer. Small size test tube is included with the wooden vase. Thankyou for looking and please don't hesitate to contact me if you have any queries. Wood height is 110mm Cordia subcordata is a species of flowering tree in the borage family, Boraginaceae, that occurs in eastern Africa, South Asia, Southeast Asia, northern Australia and the Pacific Islands.
