These stick incense holders are handmade at Bloop using Jesmonite eco resin. With a dish to catch the ash and a moveable holder. The stick of incense can be positioned at the best angle to catch the ash and it can easily be brushed away when finished.
Jesmonite is a material that resembles concrete, so each incense burner has its own unique character and texture. Packs of stick incense can be found here.
