Forto F 33 21 MM Liquid Silicone Cock Ring Medium Blue

Forto F-33 cock ring, size M

The Forto F-33 is a one-piece silicone cock ring, and this listing is the size M. Forto's hang card prints the material as 100% silicone and gives the internal diameter on a measured diagram as 0.83 inches, or 2.1 cm. There are no batteries and no moving parts: it is a single closed band of silicone with a rounded cross-section, distributed by Vvole LLC of North Hollywood, California, and sold for novelty use only.

Size M is the designation printed on the card itself, in a red badge on the front and again as F-33 SIZE M beside the diameter diagram on the back. The card gives both the letter and the measurement, and the measured figure is the one this page works from throughout. You can browse more options in Cock Rings.

A band built to stretch to three times its size

The headline figure on the back of the card is a red badge reading STRETCHES UP TO 3x SIZE. That is the manufacturer's own stated stretch ratio, and it is the reason a ring with a 2.1 cm resting diameter is not limited to a 2.1 cm fit. Silicone of this kind is elastic rather than rigid, so the band widens as it is drawn on and draws back once it is in place.

The front of the card carries two vertical callouts describing the handling characteristics Forto is selling on: 100% SILICONE down the left edge and SOFT & STRETCHY down the right. Silicone is the only material the card names.

The band itself is plain: no ridges, no texture and no hardware, just a smooth continuous ring with an even thickness the whole way round. There is nothing to charge and nothing to set.

Putting it on

Forto prints a short placement guide on the back of the card under the heading HOW TO USE A COCK RING, illustrated with a line diagram carrying four numbered positions. The instructions that accompany those positions are:

• Use water-based lubricant if needed.
• To place the ring on the shaft, simply slide it to the desired position — positions ① and ② on the diagram.
• To place the ring around the testicles — positions ③ and ④ — carefully slide in one testicle at a time.

The diagram shows placement as a range rather than a single correct spot. Positions ① and ② sit along the shaft and positions ③ and ④ sit lower, so the same ring is intended to be worn in more than one arrangement depending on preference.

Lubricant and cleaning

Forto's PRODUCT CARE line reads, in full: "Compatible with water-based lubricant only. Wash product with toy cleaner before and after each use." Both halves of that are worth reading literally. The lubricant instruction says only — it is not a preference or a recommendation, and the card offers no second option.

The cleaning instruction names a toy cleaner specifically, and specifies both before and after each use rather than after alone. The card does not mention soap, water temperature, dishwashers, boiling or sterilizing, so none of those are described here.

Wear time and safety

A warning triangle on the back of the card carries the single most important line on the packaging: "This product should not be worn for over 30 minutes. Extended use of cock rings can cause discomfort or injury. Not intended for medical use."

That 30-minute figure is a ceiling, not a feature, and Forto states it alongside an explicit mention of injury. If anything feels uncomfortable, remove the ring. The card also prints SOLD FOR NOVELTY USE ONLY and states that the product is not intended for medical use — Forto is positioning this as an adult novelty and nothing else, and this page does the same.

No California Proposition 65 warning is printed on this card. The California Office of Environmental Health Hazard Assessment publishes background on Proposition 65 warnings and a library of chemical fact sheets for anyone who wants to understand what those warnings cover and when they appear.

Who it suits

This is a simple piece of silicone rather than a gadget, and it suits anyone who wants a stretchy ring with no electronics attached. Buyers who already know they want size M, or who have measured and landed near the 2.1 cm figure, are the clearest fit. It is also a reasonable starting point for someone curious about the category, because there is no charging routine and no instruction manual beyond the four positions printed on the card.

It will not suit anyone who wants vibration, adjustability or a fastening — the F-33 is a closed loop with no clasp, so it goes on by stretching and comes off the same way. Powered and adjustable alternatives sit alongside it in Men's Adult Products. This item is for adults 18 and over.

Frequently Asked Questions

What does the 2.1 cm measurement refer to?

It is the internal diameter of the ring at rest, measured across the opening, and Forto prints it on the back of the card as a dimensioned diagram labeled 0.83" and 2.1 cm. It is not the circumference and it is not a stretched measurement. The same card states the band stretches up to three times its size, so the resting figure is a starting point rather than a limit.

Can I use a silicone-based lubricant with this ring?

No — Forto's printed product-care line specifies water-based lubricant only. That is the manufacturer's instruction as it appears on the packaging, with no alternative offered and no conditions attached. A water-based lubricant is also the one the placement guide names, in the step that says to use lubricant if needed.

How is the F-33 cleaned?

Wash it with a toy cleaner before and after each use, which is the exact method printed on the Forto card. The packaging does not name any other cleaning product or method, so a dedicated toy cleaner is what the manufacturer specifies. Cleaning before use as well as after is part of the printed instruction, not an addition.

How long should it be worn at one time?

Forto prints that the product should not be worn for over 30 minutes. The same warning adds that extended use of cock rings can cause discomfort or injury, and that the product is not intended for medical use. That 30-minute figure is the manufacturer's stated ceiling and should be read as a limit on a single session.

How is this order packaged for delivery?

Your order ships in a plain outer carton. It will not show the Gear Isle name. The Forto hang card travels inside that outer packaging, so nothing about the product is visible from the outside of the parcel.
