Repair your own gold bag! Solutions to loose or difficult to open metal parts
Hello. I am Yamazaki, a leather craftsman.
Today I’m going to introduce one of the most popular types of wallets – “ Koujin Bag ”
Since metal accessories are used to open and close, the mouthpiece may become loose or difficult to open with use.
We will introduce the structure of the mouthpiece and maintenance methods that can be easily performed at home .

Does the gold bag have the following conditions?
Unlike zippers or buttons, the most stressful part of a gold bag is of course the "gold" part.
If you find the following conditions during use, please try to perform maintenance!

Have the gaps between the mouthpiece devices caught your attention?

Did the change fall out of your wallet earlier?
First understand the structure of koujin

Koujin is to connect the left and right sides of the entire frame together with "hinges".
The opening and closing mechanism is achieved by cleverly crossing the central "balls".
Therefore, after long-term use, the mouthpiece may become loose.
If you look closely at the hinge part, you will see that the left and right sides cross each other.
By adjusting this part, you can tighten or loosen it.
When closing, push from the outside of the hinge

If the hinge becomes loose, as shown above, push each hinge inward with force.
Use both hands to wrap around the hinge and apply gentle pressure to successfully adjust it.
When released, it expands counterclockwise.

If the die is hard and difficult to use, expand it counterclockwise to loosen it.
Whether closed or open, the key is to check tightness "gradually".
Please note that if you apply force or do it all at once, the mouthpiece may be damaged. Please be careful.
If there is still a gap, you can fine-tune the handle

In most cases, by adjusting the frame, this should be possible.
But if it's still loose, you can use pliers to make fine adjustments.

Use pliers to gently press down on the handle section.
To make it easier to understand, I hold it directly in my hand, but be sure to use a rag etc. to prevent scratches.

If it is an older item, the metal mechanism of the handle may have deteriorated and become easily broken.
So be careful when doing this, do it carefully and fine-tune it gradually.
(※ Since it depends on the condition of the wallet, please bear your own responsibility!)

Adjust the left and right balls so they bite well.
The results of this maintenance are as follows:

This is a before and after picture after adjusting the loose mouthpiece. How about it? When the mouth gold bag is loose, the sound when closing it will also become dull, which is not very comfortable, so I hope everyone can enjoy the "click" sound when using the mouth gold bag.
Note: Take care of the gold zipper bag by the way, updated in September 2023.
Now that you've taken care of it, let's take the opportunity to do a little care of the wallet itself.
There are also some articles mentioning that leather wallets can be cleaned, but the sewing method of the metal device of gold wallets is a bit special.
Therefore "do not rinse directly with water".

When maintaining the fabric part of the gold bag, please make sure not to get the gold and gap parts wet.
As long as the wallet can be well protected, you can maintain it like other leather wallets.
When everything is clean, proceed with the overall cleaning bit by bit.
・Dilute neutral detergent with water, apply it on a cloth, and wring it dry.
・When cleaning the whole piece, avoid getting the metal wet. If there is dirt inside, you can "pat" the key parts to slowly remove the dirt.
・Use a wrung-out cloth containing only water to wipe with water to ensure that no detergent is left behind.
・Use a dry cloth to wipe.
・After cleaning the wallet, use special care cream to moisturize it.
・Relevant information about simple care of leather products is also compiled here, please refer to it.
・Use daily necessities to maintain leather products.
・This time we introduce a zipper maintenance method that can be easily performed at home.
We will continue to introduce troubleshooting and maintenance methods for small leather items, so please be sure to check it out next time.
So that's it. Thank you everyone.
