Product developed by Dr. Awaya.

This test features a variety of tables for different uses. Table 1 is a figure of a "swallowtail butterfly" for qualitative examination, and in the second table the cuboid figure appears to stand in front. The third table features concave on the other side. There are people who can easily see the figures that appear to emerge, and some people can easily see the figures that can be seen in the opposite way, so it is convenient to inspect the stereoscopic view of both species.

This product includes the stereo test and Red/Green Glasses. Testing distance of 40 cm.
