It's clear that #Azul is a favourite. This means, though, that the hard tiles get scrubbed about so much the dye wears off.

Preparing my newly-purchased set with some clear varnish applied to both sides of every tile.

The #DIY spirit inspired me to grab some discarded cardboard and make an origami box to store the factory bases as well.

The varnish, when dry, doesn't seem to have changed how the tiles look. So hopefully now it'll be pretty for many years of play!
