Do you know about PU leather bags?
I've always been curious about it, but my impression was that it was cheap!!

Yes, PU leather bags are quite cheap.
But actually, I didn't know what PU leather was.

So I was wondering, "why is it so cheap even though it's leather?"

Well, I've done quite a bit of research on PU leather, so I'd like to introduce it to you.

Isn't PU leather leather?

The first thing I learned about PU leather was

Actually, it's not leather!!

That is it. Lol

I was totally surprised because I thought it was all leather.
In other words, it's synthetic leather.

What kind of synthetic leather is PU leather?

The PU in PU leather is made from polyurethane.
It's a type of fake leather.

By the way, there is also something called PVC leather.
This is a very different material, so I'll talk about it another time.

Advantages of PU leather

The good thing about PU leather is, of course, that it's cheap!
What's more, it is supple and soft, with a texture similar to soft leather, making it feel closer to genuine leather.
This is the highest quality fake leather.

It is less susceptible to dirt than leather.

The bad side of PU leather

Using it in a humid environment may cause a chemical reaction with the moisture, causing the surface to crumble.
This is called hydrolysis, and once this happens it cannot be repaired.

Compared to leather, it does not age like leather and has a shorter lifespan.
The lifespan is said to be approximately 2 to 3 years.

It has a slightly shiny feel.

Summary and Thoughts

This time we introduced PU leather.
In short, although PU leather is not leather, it is a high-quality fake leather. Although it is resistant to dirt and water, it is at risk of hydrolysis if kept in a humid place, and for better or worse, it is not breathable.

Hmm. I've put together a lot of information this time, but I can't say it out loud,

Not really.

Well, you see, leather can be used for 10 years, while PU leather falls apart in about 2 years, and PU leather is cheaper though...
So, I can't help but think, wouldn't real leather be fine?

Well, I guess it depends on the person...
