So far they stack well with some given spinners of course. Tina chips will always have a few spinners. Too early to tell as more time is needed, but so far it's good. The texture does help, but probably need a few more games to get a better idea of the friction durability over time. If I had to guess now, I think they will hold enough stacking friction to my liking.
They definitely don't stack like Paulsons of course, but the table we play with is sturdy enough to have them stacking well and the table won't move if someone bumps it. If you have a light table and someone bumps it, I would say these won't knock over easily.
Well, over time I will get a better idea if I should keep my Paulsons lol. I don't see myself needing more than one set.
One thing I can say for sure is they are not as slick as Dunes "nexgen" or whatever those technically are.
