Custom goalie mask question

If you remove a mask from a goalie it's gone for good.  Same with jersey numbers and captain items.  They are one time use.

It's gone, unfortunately you cannot equip a custom goalie mask and then unequip them...once equipped they're either on your goalie or gone for good...same goes with all of the other customization items (Numbers/Celebrations/Captaincy/Goalie Masks) as well....admittedly this would be nice to see changed.
