I just bought a LV Neverfull in Dameir Ebene and here was my experience:
I was traveling during the holidays, so I went to a store out of state (my normal store would be the one in MN) that I usually wouldn't go to, and got VERY lucky with a SA who let me buy a luggage tag with my neverfull. For reference, I was in Chicago, and went to the Oakbrook Mall (Don't bother trying with the Michigan Ave location-- they wont sell you a luggage tag without buying luggage). Since I was in the store the day after Christmas, I didn't actually get it right away. I "prepaid" for it, and they said when they get it in store, I can call them and tell them what I want hotstamped, and then they would mail it to me. I asked what size I could get, and my SA told me there was only one "standard" size, and that's what I would be getting. It didn't seem like I had much of a choice for the size. For reference my receipt says .45 so I'm not sure what size that actually is. Maybe the medium or the large?
About 2-3 weeks after Christmas, I got a call that it arrived and told them what I wanted on it. They then shipped it to me with 2 day shipping and I got it about 3 weeks after I had originally ordered it. Interestingly enough, I had gone to my normal MN store in the meantime, and asked them an unrelated question, but the SA there told me that LV Corporate said in the summer of 2018 that no stores in America were allowed to sell luggage tags without buying luggage, and that whoever my SA was in the Chicago store was really lucky. She said there are some stores that will allow it, so it sounds like if you can find one, you got really lucky. The MN store told me they would NEVER have sold me one, even if I had asked the store manager.
Here's a picture. I'd be curious to know what size this actually is. For reference, I got the medium letter sizes, with no spaces in between, in gold.
