This incredibly strict open mouth gag takes things to the next level. There is absolutely no escape from this gag, it's so restrictive you will love everything about it (your sub won't!)
Have a sub who needs an attitude adjustment? Look no further, this will keep his or her mouth open whether they want to or not..

Do this one up nice and tight, and there is zero chance of manipulating the rigid steel frame, or pushing it out / flipping it etc.

Every part of this gag is top quality, from the genuine leather wrapped ring, to the heavy duty hardware and the D-Ring on the head strap allowing for a range of attach to's.


Handcrafted by us here at Mercy Industries, designed with love and experience.

~The steel ring is hand-wrapped in quality leather and come in three sizes, all measurements are given below.

- All our gags are made from soft thick luxury leather, much gentler on the face than belting leather used by many manufacturers.

~ About us ~

Mercy Industries is a premium leathercraft business located in Queensland, Australia. We design and hand make a range of leather items from the highest quality materials.

Whilst many manufacturers use synthetic or composite/bonded leather, which while they look similar, vary greatly in quality from Full Grain leather. Full Grain is the finest quality leather available, and is known for its durability. If you have ever had a leather item crack or tear and noticed the inside is fluffy and is easily pulled apart you have experienced the flaws of composite/bonded leather. Full Grain leather will not deteriorate in that way, and instead will become softer and more supple over time.

Synthetic and composite/bonded leather is significantly cheaper, and unbeknownst to most people can still legally be marketed as 'genuine leather'. We at Mercy Industries understand the frustration of buying 'genuine leather' items that don't last the test of time, and it is this experience in part that lead us to start making our own products.

This is why when you purchase a Mercy Industries product you can be confident in knowing that it will never be made from synthetic or composite/bonded leather. Further, to match the premium locally sourced leather we utilise only the highest quality durable hardware, so that all parts of our products will endure heavy use for many years to come.

We at Mercy Industries are passionate about creating unique, practical and durable leather products. We take pride in hand making each individual item and love that they each have their own quirks while still keeping to our high product standards.

If you see an item you like that is not currently available in your size, please contact us as we are happy to make custom sizing. Also if you have any specific designs that you would like created we would love the opportunity to work with you to bring your ideas to life.
