Hidden in festive layers a duo of warmth awaits!!

Woven whispers of deer for your weary soles, to warm your soul

Took a break to do some poppin, quite infernal

Now I'm just salty and sweet

Ready, for you, it's time to eat

Can be use everyday.

Can be use at home and office.

can be used for coffee or water.

Clue 1:

I have a neck but no head.

I have two arms but no hands.

Clue 2:

Talk less observe more.

Say bye-bye to carpal tunnel syndrome with me! >_n

I have space but no room

You can enter, but cannot go in

I have a lot of keys, but cannot open any locks :(

I have a neck but no head, shoulders but no arms, and I can be any color I want. What am I?
