I do like using Holy water and I phoned two of these Catholic church's I attended as a child and they expressed to me that they blessed the water that you can take home freely or use to make the sign of the cross. You can use a small container bottle to take some water home with you.
I went to the Catholic church I was baptised as a child and I loved their container in metal for the Holy water which had a dispenser and ended up filling one bottle and it was precious to me.
Today I also do at times ask my Anglican ministers to bless Holy water for me after the service and they have always obliged..It is just generally for against evil and for God's purposes which is unknown to me. I also have prayed and ask God's Spirit to bless it for me at home at times of emergency-but I do use the community that is out and it is their profession first.
I took a photo of the Holy water container in a Catholic church last November and perhaps you may be inspired to get some Holy water from church once in a while. All the best
