Forto F 33 21 MM Liquid Silicone Cock Ring Medium Glow

What the Forto F-33 Size M Glow is

The Forto F-33 is a one-piece silicone cock ring in Size M, supplied on a hang card and sold for novelty use only. The card states the material as 100% silicone, prints an internal diameter of 0.83 inches (2.1 cm), and names this colorway Glow. It carries no battery and no electronics — it is a single closed loop of silicone, and the front panel describes it as soft and stretchy.

Forto is a brand distributed by Vvole LLC of North Hollywood, California. This listing is for the Size M ring in the Glow colorway, item number FO-225-13M. See more in our cock rings category.

The Glow colorway

This is the glow-in-the-dark version of the F-33. The back of the card prints the swatch name GLOW beside a pale green dot, and the front panel prints GLOW IN THE DARK across the center of the ring. The silicone is a soft, pale green.

What the card commits to is the colorway name and the GLOW IN THE DARK marking on the front panel. On the card, the band is a single uniform pale green across its whole circumference.

Fit and stretch

The F-33 Size M has a printed internal diameter of 0.83 inches (2.1 cm) at rest, marked on a labeled diagram on the back of the card. Beside that diagram, a red badge reads STRETCHES UP TO 3x SIZE.

So there are two figures to work from: a 2.1 cm resting aperture, and silicone rated by the manufacturer to stretch to three times that size. The ring is a closed loop with no adjustment, so the resting diameter and the stretch rating are what determine whether this size suits you.

How to use it

The back of the card carries a panel headed HOW TO USE A COCK RING, with a diagram marked at four numbered positions. The printed instructions cover lubricant and placement:

• 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's numbering corresponds to those placements, with 1 and 2 on the shaft and 3 and 4 at the testicles. The manufacturer's wording is to slide the ring to position, and to add one testicle at a time.

Care and lubricant compatibility

The PRODUCT CARE line on the card reads: "Compatible with water-based lubricant only. Wash product with toy cleaner before and after each use." The lubricant instruction is a restriction rather than a preference — the card names water-based lubricant and no other type.

The cleaning instruction specifies a toy cleaner, and it specifies both before and after each use rather than after alone. Follow it as written.

Safety and wear time

A warning symbol on the back of the card is followed by this text: "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 set by the manufacturer, and the injury language is printed as part of the same warning.

The card also prints SOLD FOR NOVELTY USE ONLY. If you have a medical condition or take prescription medication, speak to a licensed healthcare professional before using any product of this kind. This card carries no California Proposition 65 warning; the state's warning program is explained on the OEHHA Proposition 65 site, and the individual OEHHA chemical fact sheets cover the substances the program lists.

Who it's for

This is a product for adults 18 and over who want a simple silicone ring in a glow-in-the-dark colorway at the Size M fit. It is the plainest kind of item in this category: one part, one material, and a short set of printed instructions to follow.

Because it has no electronics, there is nothing to charge and nothing to replace. If you are new to our adult toys category, this is a straightforward place to start.
