The Rod 8mm is a smooth, straight-shaft sound with a uniform 8mm (24 Fr) diameter from tip to base — no taper, ribs, or expansion zones, and a bore option available for those who want fluid drainage or injection. Available in six lengths from 4" to 16".

Details

  • Shaft diameter: 8 mm (24 Fr) — uniform full length
  • Available lengths: 4", 6", 8", 10", 12", 16"
  • Base: Flat safety flange

How it works

The gently tapered tip guides in smoothly, then the shaft holds its 8mm diameter all the way to the base flange, keeping pressure even throughout without any expansion zones or retention dips along the way.

Length guide

  • 4": stays within the penile urethra, well short of the pelvic floor bend
  • 6": reaches the base of the penis and perineum, just in front of the external sphincter
  • 8": moves past the pelvic bend and external sphincter
  • 10" and 12": extend through the posterior path and enter the bladder cavity
  • 16": well beyond standard urethral anatomy — the remaining length coils inside the bladder, built for extreme-length exploration

Choosing your silicone firmness

Bob recommends #10 (Medium) — it lets the longer 8"–16" lengths navigate natural curves easily while keeping the 8mm profile precise against tight muscle walls.

Color options

#18 and #30 are available in pure translucent.
#00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.

Please note

This is calibrated to a uniform 8mm profile, best suited to users who've already moved past slim starter sizes.
Use appropriate lubrication and never force insertion. Stop immediately if you experience pain, bleeding, or significant discomfort. Inspect the sound before each use and do not use it if damaged.

Grabbed it in its 4 inches + bore hole configuration for lube injection. Hardness 18A is still soft and stretchy enough for me to force a plastic syringe through the 3/32" bore hole, while staying securely in place. The rod itself slides in very smoothly, perfect size to use even with no prior stretching (I say this having almost only used 5 mm before). Translucent colour looks really nice and helps with the cleaning.

This was simply excellent in all regards! Well made, easy to use, no gripping or abrasive qualities and will definitely be coming back! Thanks!!

Smooth as silk the #18 Softness gives me a pleasurable experience with an effortless insertion. the tip is shaped well and passes through the sphincter with no undue forcing effort.
