Grave and ceremonial crosses. Grave crosses are made of solid natural oak wood, treated with a special, weather-resistant coating, which allows them to stand in the open air throughout the year with almost no changes in appearance. The ceremonial cross is made of solid natural black poplar wood. It is made in the form of a large-sized jewelry with a high-gloss varnish coating and fully corresponds to the status of exclusive sarcophagi. It is mostly used in funeral processions and farewell ceremonies.
