Recommended for open bore options

SSND-Slug is classified in the Advanced sizing tier due to its massive 20mm peak diameter, this piece opens with a tapered 5.8mm entry tip that rapidly expands over a 3/4" section into its dramatic primary dilation bulb. Following the maximum expansion point, the body slopes down to a stable 14.5mm body shaft before stepping into a 10.5mm retention valley and terminating at a wide 22.1mm safety flange. The deep anatomical notch seats safely behind the internal sphincter, locking the piece securely in position for extended retention wear.

  • Lead-In Tapered Tip: Tapered 5.8mm entry tip designed for smooth initial placement before rapid expansion.

  • Rapid Expansion Bulb: 3/4" tapered expansion zone surging directly into a 20mm (60 Fr) primary dilation bulb.

  • Sloped Body Shaft: Tapered transition down from the main bulb to a solid 14.5mm (43.5 Fr) mid-shaft.

  • Sphincter Retention Valley: 10.5mm (31.5 Fr) structural notch engineered to anchor securely behind the sphincter.

  • Wide Safety Flange: 22.1mm (66.3 Fr) base flange preventing over-insertion and ensuring easy, controlled removal.

The SSND-Slug features a total length of 5 1/8 inches with a 4.5-inch insertable depth measured from the entry tip to the retention flange. This total length allows for full-body urethral coverage and secure anchorage during use.

👑 Bob's Choice Recommendations

  • Experience Level: Advanced

  • The Prime Durometer Recommendation: #10 (Medium) silicone density is strongly recommended as the default choice. It provides the ideal column strength needed to push the 20mm bulb into position without flexing or buckling.

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.
