Can I use the word "conjoin" in this kind of sentence?

Hi guys!
I need help with the word "conjoin." I already have an idea what the word means but I don't know if I can use the word "conjoin in the sentence below.
"Conjoin this pen along with those in the bag."
Can I use the word "conjoin" in this kind of sentence? What I'm trying to tell in this sentence is I'm asking someone to put the pen in the bag along with the other pen.
Thanks.

No. Stick with 'Put the pen in the bag along with the other one'.

It is a very formal word- it's a word I might read occasionally, but I never use it.

I've only heard the adjective form in 'conjoined twins' (formerly called 'Siamese twins').
