Hello, if I have several different UTXOs (mixed) in one wallet and I make a transaction, could the receiver see all of my UTXOs in the wallet or just the one they received?

Thank you!  

 They can see all the UTXOs that you spent to fund the transaction. 

 Ok great. So if I were to select 2/10 UTXOs for the transaction, they could only see the 2??

Thanks ! 

 Yes, they can see only the 2.  

 Assuming no address re-use, right? 

 Correct.
