Hello everyone! hoping someone can help me We sell Magnetic memo boards that come with a set of either 4 or 8 pens.

We also sell the pens separately which we’re due to create a new ASIN for as we’ve not got it on Amazon yet.

I know how to combine ASINs. But my question is, are we allowed sell this set of “spare pens” in the same listing. As we want our customers to have the option of buying spares, as it’s often asked.

I’d imagine Amazon would let us combine them, but my question is more if that breaks the rules or not. As it won’t be another memo board, but rather a spare part(s) for it.

thanks Very much everyone!
