Want to measure or improve your gape? This is the tool for that! Available in either medium or large size, these cones are marked according to the diameter you work up to.
On the medium size (shown in gold pearl) the rings indicate what the size is right at the top of that ring. Starting at one inch diameter, then going up every half inch to two and a half inches diameter. The total height is seven inches.
On the large size (shown in black pearl) the rings indicate every inch in diameter from one to four inches, with the bumps in between indicating half inch increments. The total height is eight inches.
The use of raised rings and bumps enables one to feel the measurements as one progresses so you can be sure of how far the hole is stretched in any situation.
