Oops!

This kit definitely qualifies as unusual and a little scary by most peoples standards. This set of 10" probes is made of chrome-plated brass. Each probe in the series is slightly larger than the one before and slightly larger on one end than on the other for a total of 16 graduated sizes from just over 3/16 inch in diameter to about 1/2 inch. The original intended medical use for these probes was to dilate the cervix but they were also used to clear blockages in the urethra. With this kit even the smallest size is probably too large for a beginner to insert. For people with a fetish for bizarre old medical paraphernalia these kits are a find. The tubes are rounded at each end and they come in a high-quality zippered dark brown leather case with red velvet lining on the inside. Sold as a novelty not recommended for actual use except under the guidance of an expert.
This extra long kit differs from the Basic Probe Kit in the following ways: The probes are 2" longer and heavier. They have a slightly different shape and the diameters are different as well. Note that the 8" probes on the basic kit also cover a greater range of diameters on both the larger and smaller ends.
