Find the urge to go deep with insertion?   This Medical grade, hollow silicone insert may be just what you are looking for. At 13" in total insertable length, it will definitely hit any depth you want it to.  Totally hollow with a soft smooth touch and comes with two gland rings (1" and 1.25") and ring holder to keep it in place.  It also has a plug that can be used if desired, to keep fluids in place until you wish to unload.

This insert is not made of conductive silicone and is not intended for electro-stimulation. Can be used in conjunction with e-stim for added excitement. If you want to shorten the insert, one might carefully cut it to length at any of the rubbed sections.  Just make sure when doing so, you don't leave any edges that could cut the inside of the urethral canal.

After use, it is highly recommended that you flush the hollow tube with hot water and antibacterial soap.  To make sure no bacteria remains, you may want to get a pan of water and bring to a slight boil and immerce the insert into the water using tongs, making sure the hot water moves through the insert.   You do not need to leave the insert in the water for very long.  Just enough time to get the water throughout the insert.  Leaving it in too long may cause the silicone to disfigure or even melt.  :(

Two diameters are available; 5.5mm and 7.5mm.  Be sure to indicate the size you want in the Drop-Down Box below.
