The L'Occtaine one may not be made as good as the first Plisson one but it's still a good deal at $30.00.
I have cut many of these apart and noticed that the ones marked as Plisson only are made from a dense, dark colored wood and the ones marked with Plisson pour L'Occitane is made from a light colored wood, probably beech wood - which is also dense, but not as dense as the dark colored wood.
Also, the knots of the Plissons is set totally in glue while the L'Occitanes often barely touch the glue (looks and feels like hot melt glue).
This might be the reason that the L'Occitane knots often fall out.
