Libbey Gibraltar stackable series
Compared to the regular Gibraltar series
these glasses show a seminal difference: The rim between the rounded lower and the faceted upper half of the glasses was widened and shifted to the center line because it also serves as an edge for this stackable
variant. Apart from that, the overall design is also kept a little bit more lineal. But when it comes to the quality, the stackable Gibraltar-series is of course in no way inferior!
