Daiso's $2 Vacuum Container: Can It Actually Hold for a Week?

I’ve put together a blog post summarizing what I covered on my YouTube channel.

For those who prefer watching, I’ve also included the video below!

I found these vacuum storage containers at Daiso for just $2–$3.

At first, I was skeptical: "Can it really create a vacuum at this price? And even if it does, will it last a whole week?"

I'm kiit, your reviewer.

I've put this Daiso vacuum container through various tests to see if it lives up to the claims.

Can it really maintain its vacuum state for seven days?
