Stockage tips
Carry your inner tubes in a container that protects them from perforations (tool case, original packaging, etc.).

Rubbish
Used for 1 week or less
Cheap but very much not cheerful. Replacing a punctured tube with this, only to find out it's already leaking air.

Found the hole and repaired it with a patch and still leaks.

In the end I patched up the original tube and gave up on this one.

Usually like decathlon stuff but will not buy inner tubes from there again.
Response of the brand
I'm sorry to read that the innertube was punctured straight out of the box. This is highly unusual and I am unable to explain why it's the case in this instance.
