SSND-MDCUBE 10-24mm (30-72Fr) 9" Multi-Diameter Stretching Sound

Here is our revolutionary CUBED or squared design, which we have applied to the multi-dimensional flexible urethral stretching silicone sound insert family. With its smooth-edged tip at approximately 10mm diameter, this one is perfect for the seasoned sounder who wants to move into the more aggressive stretching area to make use of even larger sounds. Similar to our MD 12-21mm stretching sound mixed with the original squared design characteristics of our MRB-CUBE, we have fashioned a gently sloping 9-segment design that gradually increases to the next larger stretching diameter of each segment, with just a minimal retention valley before expanding up to the next segment.  Please view the cross-sectional labeled photos for an up-close assessment of the dimensions.  The total length of this probe is 9” with an insertable length of approximately 8.5” up to the flange with a deeper retaining valley of 20mm diameter just in front of the base. This probe can be purchased with an open core for extended-length wear to accommodate drainage or with a completely solid configuration. Open core options are available in the drop list box.   

This sound has 9 separate segments sized as follows. The first number is the largest diameter of the segment, and the second number is the accompanying retention valley diameter for that segment. 

1 - 11/10mm - Approximately 33 to 30Fr

2 - 12.5/11.5mm - Approximately 37 to 34Fr

3 – 13/11.5mm - Approximately 39 to 34Fr

4 – 15/13mm - Approximately 45 to 39Fr

5 – 15.5/13.5mm - Approximately 47 to 40Fr

6 – 18/15.5mm - Approximately 54 to 47Fr

7 – 19.5/18mm – Approximately 59 to 54Fr

8 -21.5/20.5mm – Approximately 65 to 62Fr

9 -24/20mm – Approximately 72 to 60Fr

The silicone material is very flexible in the smaller diameter regions but still quite firm when ordered in the #18 silicone, which I recommend for a moderate level of stiffness. If you want it to be as soft as skin, you can choose the #00-20 or #00-50 softness level, which is still quite soft and compressible. This is what I refer to as the compressible softness levels and is actually a spongy feeling. The #00-20 is the softest. This softness is really nice because it will allow the sound to compress upon insertion and then exert a continuous outward pressure to stretch the urethra to the selected size gently. The softer material, the more compression. Liberal amounts of lubrication allow this sound to be inserted to the desired expansion size while at the same time remaining comfortable and stimulating for extended wear if that is what you desire.

 The #18 and #30 are the only silicone that we have available in pure translucent. The #00-50 and #10 base color are a translucent white but can be mixed with all our standard color selections. 

Enjoy!
