Our models are made with great care, using high quality materials and a matt protective varnish. They are packed in a plastic PVC cylinder box. Upon removing the top of the box, the models can be easily pulled out of the sponge base. For the installation of the models, depending on the model, a hole with a diameter of 3mm, 4mm or 0.7mm must be made in the ground, and we recommend “Tesa” universal liquid solvent-free adhesive for gluing them in.
