HISTORY

ABOUT US

My name is Jacob Cho and I have 2 children.
I was experienced a water emergency and my mind was confused.
So I let my children learn to swim.

Just learn to swim doesn’t get you out of a water emergency. So I developed S tube.

S tube is a life-saving product in a water emergency.
Now you just have to play with the S tube.

NETF Inc. offers S tube on different sale platforms like online stores.
B2B requests are welcome.

NETF Inc. was founded in 2017. The company is located in Seoul, KOREA.
