30 miniature-sized tetrapods. Size is approximately 1cm. Created with a stereolithography 3D printer. I think they can be used for N-gauge dioramas, etc. The freight car in the photo is an example of loading and is not included. Please note that there may be traces of support material removal. Please purchase if you understand that this is a amateur creation. If you purchase other items at the same time, we will discount the shipping cost. Please consult us for changes in other sizes and quantities.
