The OP04 is a versatile strip of natural stone that can be perfectly placed between two types of ground cover, such as pebbles and soil, to ensure that they do not mix with each other. Thanks to the loose placement of this strip, you can easily change models later or, for example, choose to only place pebbles during the winter months. You can simply place the strip behind the grave, making maintenance and adjustments easy. Available in black granite, Bianco Carrara, French limestone, Belgian bluestone, Teakstone or Corten steel. The OP04 is a durable and stylish solution for customizing your grave monument.
