Finally, several weeks ago, I managed to acquire one through an online site, and eagerly awaited its arrival. Only to have it arrive with almost every stone having new chips and one critical stone broken in half.
Eventually I repaired the broken stone, resigned myself to the chips, and today I finally built with it.
Wonderbrix sets, at first glance, seem to have their stones in the size
series familiar from the regular Lott's sets, and closely akin to the
Ankerstein sets, but in fact they are off a bit: ~3/8" x ~1 1/8" x ~1 7/8".But they are still well-suited to building, and have a very satisfactory feel. I am glad to have them.
Good Block Play.
