Ragno wall tiles. 200mm x 250mm (about 12 - 13 sq. m.?). I think there’s around 270 of them, but they’ve been stored for a few years and moved a couple of times so there are probably a few broken ones. Boxes, as can be seen from the photos, are pretty well ruined, but the tiles themselves are fine. They are gloss white with a faint grey/cream/fawn haze through them, which I’ve tried to show in the photos. Collection only, I’m afraid, these are pretty heavy!
