Guess the container

I have quite a few samples waiting to be tested. I was going through my stash of them, and decided to try a Stirling. But I didn't have any spare container and my wife gave me a look when I asked if she has one. So I decided to be 'creative' and use the following plastic case as a temporary soap container.

Can anyone guess what was inside? (Hint: The 'thing' that was inside this will also be used in this hobby of ours)

Shea butter?

No, Freddy. My shea butter containers are still full. The 'thing' has to be taken out of the container to be used. And afterwards it can be stored anywhere, without a case.

3m tape

3m tape

Wow. That didn't take long. Yes it is. For honing/refreshing my razors.

Industrial electrician use it about everyday. Black,red,blue,green,white,gray,yellow,brown,orange I'm sure there's more.

Wait a second! 3M tape? How does anyone guess 3M tape? 4M maybe, but 3M?

3M is the brand.
