I'd love to know how to get one too, if possible...

Correct. The plastic ones were discontinued years ago and now the round rubber ones are produced. Back when the hard plastic ones were used, there were very few TT members so it was much easier for Titleist to budget giveaways to the majority of members. Over time the membership has skyrocketed therefore things like bag tags are given mostly to attendees at events. This guarantees they get to loyal members and not individuals that just sign up to post a complaint or to try and get free merchandise. If you cannot attend one of the big events, look for a local outing near you. They would occasionally be posted on the “Events” tab or under the “Travel” topic. Save the old one, they are getting pretty rare.

Doubt you'd find one unless you're on Ebay.. That's an Oldie but Goodie!

If you attend just about any Team Titleist event you will most likely be given one of these. By the way, that is an old version of the current Bag Tag...
