Recommended for open bore options

The GRB228-16" is a very large graduated colon tube with a rounded 1" tip that gradually increases to a 3" diameter shaft. The tapered section continues for approximately 10" before reaching the first 3.5" retaining ball.

Behind the ball is a 1 3/4" long retention valley that narrows to approximately 2.5" before reaching the final 3.5" base section. The final section is not intended for insertion.

  • Overall length: approximately 17" (43.2 cm)
  • Insertable length: approximately 12.5" (31.75 cm)
  • Tip diameter: approximately 1" (2.54 cm)
  • Tapered section: approximately 10" long
  • Main shaft diameter: 3" (76 mm)
  • Retention ball: 3.5" (89 mm)
  • Retention valley: approximately 1 3/4" long × 2.5" (63.5 mm) diameter
  • Final base section: 3.5" (89 mm)

Choosing your silicone firmness

For a piece this large, Bob recommends choosing a softer silicone. #00-50 Soft is a good starting point, while #00-20 Very Soft is available for an even softer and more flexible piece.

Color options

#18 and #30 are available in pure translucent silicone.

#00-50 and #10 use a translucent white base and can be mixed with our standard colors.

Please note

The GRB228-16" is an extremely large design. The main shaft reaches 3" in diameter and the retaining ball reaches 3.5". This piece is intended only for very experienced users who are already comfortable with very large-diameter designs.

Anatomy varies, and no single size or shape will work for everyone. Use appropriate lubrication, never force insertion, and stop if you experience pain or significant discomfort. Inspect the nozzle before each use and do not use it if damaged.

Exceptional stretcher, the taper feels amazing!

I am in love with this toy. I ordered the 0020 softness and No Bore (Solid) options. I have been taking 4" toys for years, so I'm not a novice. The tip is incredibly flexible and sways where it wants to. I can squeeze the tip and compress it with my fingers quite easily, so it can easily navigate my sensitive canal. I can also significantly compress the neck just past the retention (first) bulb, and I love squeezing it with my anus. The safety flange (second bulb) has a flat spot on the bottom, which is nice for putting on the floor and rocking back and forth while the retention bulb is humping my prostate. I have been able to insert the toy backwards, though I haven't yet gotten over the second bulb.

If SN put another taper at the back end of this toy, I could see it being used with a partner as a tug of war toy (maybe elongate the neck a bit more to make sure each person has enough room to slide onto.) Oh, now I want another one of these. Maybe offer a shorter taper so women can insert it vaginally, too?

My toy is ~16 1/2" long (photo has a parallax effect.) From tip to taper is 7 3/8", and the retention bulb is 3 1/8" long. So from tip to the bottom of the retention bulb is 10 1/2". Total usable length is ~13".

The taper is about 1" wide at the tip, going up to 2 3/4" wide just above the first bulb, and the resting channel is 2 1/2" wide at its narrowest. Both bulbs are 3 1/2" wide.

This is an amazing toy with some exciting opportunities. I highly recommend it.
