[Grammar] It was/ I have

[aceidiot]

Which one should I use?
1. "I used to have a Justice League bag when I was younger. It was the coolest bag I've ever owned."
2. "I used to have a Justice League bag when I was younger. It is the coolest bag I've ever owned."
3. "I used to have a Justice League bag when I was younger. It was the coolest bag I had ever owned."

I want to know which one has the same meaning as "I don't own this bag anymore but none of the bags that I've bought have been as cool as this one." I just want one that sounds natural during a conversation. I want to emphasise on how cool the bad was and that I haven't found a bag as cool as that one was/(is?).

Please correct any mistakes I've made.

Edit: Sorry for not capitalising the brand name.

The first thing you need to do is correct the lack of capitalisation in the brand name of the bag you owned. Look up the name of that film franchise somewhere and then copy how they capitalise it.
