The last purchase contain,

A device to add to the top of a can to disperse the contents, it was made by the same manufacturer for which I bought the spray way back in 2016-17. (won’t post that)

I posted a shot of the heart that was done that way, may have had the words one love or mi luv yu bad not too sure. You can tell these ones as they have slight scratches on them.  The ones lost to me where very clear indeed, then if anything sprayed with the matte varnish. They were not as easily scratched. Shame I no longer have them.

The below shot is what remains beyond the the two I have. The design mark that is missing and the middle one on the bottom row (tile that is)

Colour is not the matter
