Single Strap Leather Open Mouth Ring Gag - Black Ring

Our standard sizing will fit most people due to their designs and generous adjustability. However, if you require custom sizing we offer this at no extra cost. Simply enter your relevant measurements into the customisation field on purchase and we'll take care of the rest. 

Please note, we don't require perfectly accurate measurements as we’ll craft your piece with room to adjust. This also allows you to wear it tighter or looser depending on your preference. If you do have any fit preferences just include these as well in your instructions. 

If you have any questions at all regarding sizing or fit, please don't hesitate to reach out to us!

Please see below instructions for measurements for each type of product. If you don't have a flexible measuring tape you can use a string and then place this on a ruler to get the circumference. 

Collars

• Wrap the tape around your neck where the collar will sit. 

• Keep it level and snug without squeezing.

• For our martingale collars please just measure your neck circumference at the base and we will make it to the correct size. If you have a preference for tighter or looser fit please note this in the customisation section on purchase.

Wrist Cuffs

• Measure around your wrist where the cuff will be worn.

• Keep your hand relaxed and the tape comfortably snug.

Ankle Cuffs

• Measure just above your ankle bone, where the cuff will sit.

• Stand naturally, without flexing your foot.

Thigh Cuffs

• Measure around the part of your thigh where the cuff will sit.

• Keep your leg relaxed - don’t flex or tense the muscle.

Upper Body Harnesses

• Bust/Chest: Measure around the fullest part of your chest.

• Under bust: Measure around the area directly under your bust.

• Waist: Measure around your natural waist (narrowest part of your torso).

Lower Body Harnesses

• Waist: Measure around your natural waist (narrowest part of your torso).

• Hips: Measure around the fullest part of your hips/butt.

• Thighs: Measure around the part of your thigh where the straps will sit. Keep your leg relaxed - don’t flex or tense the muscle.

We recommend gentle cleaning of your gear after use to remove body oils and perspiration.

• Dip a microfiber cloth in warm water and a few drops of dish soap, and use the cloth to wipe your leather gear.
• Avoid firm rubbing as this may damage softer leathers.
• Use a damp microfiber cloth (no soap this time) to wipe down your item.
• Ensure you dry the leather fully with a clean and dry cloth.
• You may also like to use an appropriate leather cleaner and conditioner every 3 or so months for maintenance.
• Never immerse your leather goods in water as this can alter the colour or shape and reduce its resilience.

Storing your leather gear

• Store your leather items in a natural fiber bag or a container with vents in a cool, dry space - away from humidity, heat, and direct sunlight to avoid any damage.
• Do not store your leather items in plastic or sealed containers as leather is a porous material that needs to breathe in order to stay supple and prevent mould or other damage.

Hardware Care

Our leather items are often embellished with hardware e.g. steel studs, rose gold o rings, brass buckles, etc. It’s important to care for these too.

Steel & Brass

• Gently clean with warm water, mild dish soap, and a soft cloth (a lint-free one). For buckles you may like to use a soft toothbrush to clean those hard to get to areas. Ensure you dry thoroughly with a soft cloth.
• If you prefer, you can invest in a stainless-steel cleaning formula to remove grime and prolong the sheen.

Plated Gold or Rose Gold

• Use a dry polishing cloth to remove grime and oils, ensuring the hardware holds onto its shine.
• If a more thorough clean if required you can also use mild dish soap and warm water. Remove any soapy residue with a damp cloth and dry the rose gold after, giving it a once over with the dry polishing cloth to keep it gleaming.
• Plated gold or rose gold can tarnish over time due to natural oils excreted by the skin, humidity, and skincare creams or perfumes. We recommend not using skincare products in the area prior to wearing any Rose Gold hardware items, and gently polishing after each use.
• Some people are more prone to plated metals tarnishing from skin contact - if you find this is the case we recommend an anti-oxidation protectant spray.

Avoiding oxidation

The natural process of oxidation occurs when metals are exposed to sunlight and air. Oxidation affects metals in different ways, e.g. when silver is exposed to lots of sunlight and air it may turn black over time, whereas gold may develop a dull, brown hue.  

Oxidation can tarnish your hardware and leave it looking lacklustre. Good maintenance cleaning and proper storage will keep your metals shining as good as new. You may also like to use an anti-oxidation spray to protect your hardware.

If you do find your STEEL or BRASS hardware has tarnished there are commercially available cleaning products that will restore it to its original shine. Avoid harsh cleaners for ROSE GOLD or GOLD PLATED hardware as this will damage the plating.

If you have any issues with your leather items or hardware please get in contact with us!

We ship parcels to destinations all over the world. Please be assured our parcels are very discretely packaged!

*USA CUSTOMERS: Please note, unfortunately due to the tariffs, we are no longer able to absorb the shipping costs as we previously did in addition to tariff amount. Therefore we are not able to offer free shipping to the USA at this time.
