This replica is dimensionally accurate to within 0.1 mm, making it suitable for experimentation as to the bannerstone's function and purpose, a topic debated by archaeologists.

This is made from Prusament, an extremely hard composite plastic made in the Czech Republic. Unlike common plastics like ABS or nylon, this material has absolutely no flex. This makes it identical in hardness to the original stone, which is critical for some research purposes.

Given the high cost of authentic bannerstones, this replica allows for indiscriminate experimentation and handling by students without fear of costly damage to authentic specimens.

Made in the USA.
