ABOUT
sub_story01
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.
ANITHING IS POSSIBLE
WE NEVER GIVE UP CHALLENGE
Since we developed the inflator in 2017, we have been constantly challenging the development of inflatable buoy.
DEVELOPED IN KOREA
we are constantly improving the s-tube technology for you.

It was nice to have a simple way to use it. Just pull it! And it’s nice that it can be reused. After using it, it was comfortable to float in water as it could continue to be used as a buoyancy device.

The biggest advantage is that it is easy to use and easy to carry for everyone, regardless of age or gender. A must for everyone who plays in the water! Necessary emergency buoyancy device! S Tube! Highly recommended.
