The FLOWER TUBE collection is a series of cylindrical glass vases, designed for small bouquets, single stems, cuttings, and branches. The vases are available in 2 heights and consist of a coloured vase that rests on a transparent glass cylinder. The vases are handcrafted in high quality borosilicate glass. This vase is blue but is available in a range of colours. Be aware that the edge of the upper glass is fragile. If you need to clean it, we encourage you to be extra careful when removing the vase from the cylinder. The sculptural blue Flower Tube vase brings a fresh splash of colour to the decor and invites you to experiment with different types of decoration. You can of course use a few fresh stems from the garden, perhaps in a nice contrasting colour to the clear blue colour of the vase. You can also use the vase for plants that can stand in water or for a small cutting that allowing it to unfold its root system in the transparent vase. A living little green experiment that works as a beautiful and vibrant little artwork in your decor. The glass vase can be used as part of a beautiful table setting, in the windowsill or on the shelf, where the individual silhouette and the clear blue glass capture the sunlight in the most dazzling ways and cast evocative shadows. The cylindrical vases are crafted from borosilicate glass. This type of glass endures large temperature fluctuations, so you do not have to worry about the glass cracking. The glass is scratch-resistant too ensuring the vase will maintain its beautiful blue colour as time passes. We recommend cleaning the vase with warm water and soap and perhaps a little regular vinegar. In principle, you can put them in the dishwasher, but we do not recommend it, as they may bump into other things and break. It is glass after all. Explore the series of bubble vases for the table too. They look great combined with Flower Tubes. Studio About is a Danish design studio. The entire Flower Tube collection is designed by architect Mikkel Lang Mikkelsen.
