Forto F 33 17 MM Liquid Silicone Cock Ring Small Black

What it is

The Forto F-33 is a non-powered silicone ring, molded in one piece and supplied here in size S in black. The hang card prints the material as 100% silicone and the inner diameter as 0.67 inches, or 1.7 cm, measured across the relaxed opening. Nothing on it switches on: there is no motor, no battery compartment, no charge port and no cable anywhere on the band. It is an elastic loop, and the only two things you need to know about using one are where it sits and how long it stays there.

The front of the card carries the Forto wordmark, a red roundel reading "Size S", and the two descriptions the maker leads with: "100% Silicone" and "Soft & Stretchy". Those are the headline facts, and on a product with no electronics in it they are most of what there is to say.

Material and construction

The band is a single continuous loop of silicone with a rounded, doughnut-shaped cross-section — thick through the body, with no clasp, no buckle and no adjustment point anywhere around the circumference. There is nothing to unfasten and nothing to set. The surface is a soft matte rather than a gloss.

Silicone is the reason the specification sheet is so short. It is a flexible, non-absorbent polymer, it takes a smooth surface straight out of the mold, and it tolerates being pulled well past its resting shape and returning to it. The maker puts a figure on that: a red badge on the back of the card reads "Stretches up to 3x size". Read it as a description of how far the band is meant to open during placement rather than as a target to aim at.

One consequence of the material is worth knowing before you order, and it concerns which lubricant you pair it with. Forto is specific about that on the card, and it is covered in the care section below.

Product specifications

How to use it

The back of the card prints a four-step placement diagram, and it is worth reading first because the two ways of wearing the ring are not the same operation. Use a water-based lubricant if you need one. To wear it on the shaft alone — positions 1 and 2 on the diagram — slide the ring along to where you want it and leave it there. To wear it around the testicles as well, positions 3 and 4, Forto's printed instruction is to slide one testicle through at a time rather than attempting both together. That second method is why the diagram runs to four steps instead of two.

Because the band is a closed loop with no fastening, placement is the whole technique. Open it with your fingers rather than forcing it on dry, give it a moment to settle, and take it off the same way it went on.

Care and lubricant compatibility

Forto specifies water-based lubricant only, and that word "only" is printed on the card rather than being a general suggestion from us. It is the single compatibility instruction the maker gives, so follow it as written and keep silicone-based and oil-based formulas away from this ring.

For cleaning, the printed care line is to wash the ring with a toy cleaner before and after each use. Dry it fully before it goes back in a drawer, and store it where it is not pressed up against other silicone items. With no battery hatch and no charge point on the band, there is nothing on it that has to be kept away from water, which makes it one of the simpler things in a drawer to look after.

Who it's for

This is a first-ring or a spare-ring purchase: adults over 18 who want a plain silicone loop with no electronics, no charging and no learning curve. The 0.67 inch inner diameter is the number to go on, because fit is the entire reason this model is offered in more than one size — measure rather than guess before you choose. Our cock rings category lists the alternatives if a different diameter or a different design suits you better, and it sits inside the wider sex toys range.

It is also a straightforward thing to own if you are new to the category. There is nothing to charge, nothing to pair and nothing to replace, which is not something every item in men's adult products can say.

Good to know

Forto prints a wear-time limit on the card, and it reads as a limit rather than a suggestion: this product should not be worn for more than 30 minutes. The card states plainly that extended use of rings of this kind can cause discomfort or injury. Take 30 minutes as a ceiling rather than a target, and remove the ring sooner if anything feels uncomfortable.

The card also states that the product is sold for novelty use only and is not intended for medical use. If you have any medical condition, or you take prescription medication, speak to a licensed healthcare professional before using a ring of any kind.

California's Proposition 65 program requires certain products sold in that state to carry a chemical exposure warning. The state's Proposition 65 warnings site (OEHHA) and its chemical fact sheets explain how that program works and which substances it covers. Neither page refers to this product; both are linked as general background on California's warning scheme, not as any assessment of this ring.

Frequently Asked Questions

What is the Forto F-33 made of?

100% silicone, as printed on the front of the hang card. It is molded as a single continuous loop with no clasp, no buckle and no metal or plastic parts, and the surface is a soft matte black.

What size is the small F-33, and how far does it stretch?

The inner diameter is 0.67 inches, or 1.7 cm, measured across the relaxed opening and printed on a diagram on the back of the card. The card also carries a badge reading "Stretches up to 3x size", so the band is built to be opened well past that resting measurement while you position it.

Which lubricant can I use with it?

Water-based lubricant only — that is the instruction Forto prints on the card, and it is the only compatibility guidance the maker gives. Silicone-based and oil-based lubricants are outside what the maker specifies for this ring, so stay with water-based formulas.

How long can the ring be worn?

No more than 30 minutes, which is the limit Forto prints on the card alongside a warning that extended use of rings of this kind can cause discomfort or injury. The card also states that the product is sold for novelty use only and is not intended for medical use.
