Kaiu, the meaning behind its name
Caille is a small stone, a gem.
It comes from the French word 'caillou', which has a meaning.
our children grow up in love
I hope to become a person who shines like a jewel in the future
I have a wish
accessories model image-S12L1
Since 2002, KAIU
Missile prevention necklace first launched in Korea

Caillou is the first in Korea
child's name and contact information
As a company that started engraving on jewelry,
Caille products are in an unexpected situation.
365 days a year, I have always been by your side.

20 years ago, babies became teenagers.
Growing up, now instead of the guardian's contact information
They wear jewelry with a message of support engraved on them.

Siblings, mothers and couples, all of our families,
And even now, from a baby to a teenager!
Family Jewelry Brand, Kaiu
It is growing every year.

Cailu Designer Kim Hyun-mi
I will make it with love. Will you remember me every time I see you?

Click on the image to view the interview with the author.
When I was in college, the subject of my work was Who am I?
The vague concerns of life were the subject.

But as a mother of two daughters and a wife,
Living as a daughter and eldest daughter-in-law
the true meaning of my life
made me think

'I want to be someone who can impress someone'
Put that heart into Caillou
Days accumulated year by year
More than 20 years have passed,
even at this moment
Because I can be with Caillou
Thank you.

For jewelry worn 365 days a year
Produced with the heart of the person giving the gift,
to the person who wears the gift
If I could give you my love,
If you can impress
How good would it be?

Like a necklace that conveys love
Just like a messenger.

A man cannot stand alone
like a human character
A gift with love that supports someone,
Caillou is such a gift

accessories detail image-S14L2
20 years of fame! How was it possible?
Starting a business with an anti-missing necklace
I have a promise.
“Good product, reasonable price, sincerity”.

Caillou is the designer's pride.
We produce the best products.
Only silver and gold are used.
Set with natural birthstone.

If you compare the price, it is cheap in the market
There will be a lot of material products.
However, customers who want to make a special gift
Caillou of 'high quality and reasonable price'
You have chosen.

Customers who are satisfied with the first product
Second and third children and gifts for nephews
You buy it from Caillou.
The expectations and satisfaction of each and every customer,
In order to live up to the trust that comes back
Day by day, doing my best, piles up
20 years of fame.

Click on the picture to see the story of Caillou's 12 zodiac characters.
Why did you choose the 12 zodiac signs as Caille's representative character?
The 12 zodiac changes every year
As the animal representing the year
It gives a lot of meaning,
Everyone is born with a magnetic belt.

A lost child prevention necklace with that friendly character
For me, who made and sold
Because it was such a good thing
As the years went by, I started to design, and while raising a child,
As a result of 9 years of long time
has been born

Quality, Safety and Design
High quality, safety verification, and Caille's unique design!

Caille is made with silver and gold, which are good for the body.
Safe for toddlers to use, sturdy, soft and smooth design
We are building trust with our customers.

1. Manufactured from 92.5% pure silver. (Korea Precious Metals Analysis and Appraisal Institute)
2. The only rare silver product in Korea.
* Rare silver is excellent for preventing discoloration of silver.
3. We use natural birthstone.
* There is a slight color difference between natural gemstones.
4. Chain, linkage, and locking device load tests have been verified. (Korea Polymer Testing Laboratory)
* It is a sturdy product that can withstand the load of about 9 bottles of 1 liter mineral water hanging from a necklace.
5. Caille's unique design developed by himself after 20 years

Add that heart to your natural birthstone!!
Caillou was created by hundreds of millions of years of time and high temperature and pressure.
We use natural gemstones.
Wearing a birthstone on your body is said to bring good energy and good luck.

accessories -S4L1
Unlike synthetic stones, natural gemstones have very subtle color differences.

accessories -S4L2
The unique meaning and month of the birthstone
Caille put together the cases of the East and the West.

Garnet, the birthstone for January, goes well with children's products.
I use red-violet rhodolite garnet.
March's birthstone, aquamarine, is similar in color to diamonds.
It is light water color.

✽ Pearl, the birthstone for June, cannot be engraved due to the nature of the stone.
(Ruby is preferred for girls / Topaz is preferred for boys.)
The chain is the one that best matches the product.
It is set to be selectable by default.

For first-time purchasers
Show several chains and choose
I think it's difficult
It is composed of the chain with the highest satisfaction.

Chain length can be added in the additional components of the product.

What is Rare Silver?

Rare Silver is for customers who are concerned about the sudden discoloration of silver due to sweat.
This is the product you are looking for.

Rare silver has the same content as sterling silver (Jung Eun) 92.5%.
By alloying a small amount of platinum with the remaining alloy components,
It is silver from which silver reacts easily.

Rare silver is excellent at preventing sudden discoloration due to sweat.
In addition, under conditions that change silver, rare silver may also change color.
Please note that there is.

✽ Due to the high production cost, some products cannot be manufactured with rare silver depending on the product specifications, and there may be slight stains from the alloying process.
accessories -S1L17
gift wrapping
We deliver Caillou's love in a luxurious gift package.
We improve the quality of packaging through our own design and production,
We tried to lower the production cost.
