Square pearlescent tiles

[notasausage]

Anyone know where does these. Saw them in B&Q a few years ago but they don't seem to have them any more. They were about 10cm sq

these?

That looks like the thing. Need to find a local retailer though as had terrible experience buying tiles online in the past and not keen to make the same mistake again - mosaictileshop I'm looking at you ...

I've bought tiles on line, I think from those people in the link. They were fine

Can you get them to send a sample and see what the service is like first?
