Well, I've sported a mustache for going on 50 years. Until recently (5 years or so), I really didn't need mustache wax as my mustache was long and soft enough to stay put once combed. However, that changed when my mustache turned from dark color to, well, more gray than I care for. When the color changed, so did the texture of the hair, going from soft to wiry and unruly. Made it look more like bushy eyebrows stuck on my lips than a mustache. w
I have tried wax before, but it has been many years, and that stuff came in a small toothpaste like tube that came out thin, then dried to a hard wax that made the mustache look like it had been plastered in place.
So I tried Texas Beard wax. I hadn't seen wax like this before, so was surprised if find it nearly as hard as candlewax. It took a bit of learning to apply it, but it works after figuring out how to get it on. A lot of finger and thumb circular pressure while getting it on the digits, to be able to transfer to the 'stache. It takes a bit of doing, but the results are satisfactory and keep the unruly hair in check. Daily use helps to 'train' the hair to behave and stay in place. Used after a beard softening oil helps to hasten the training process.
Not sure why such a small amount costs as much as it does, but it should last a good, long while.
Now, if it weren't for the dumbass mask rules in airports and such, the grooming would stay in place much better and longer.
