Well I saw the picture and read all the way to the end and am now really intrigued about that mystery purchase.

I re-looked at the picture to see if there was a clue in the remaining stock; I used photoshop and that thing it does to check out all the colours; re-read the whole of your post (twice), but I was stumped.

Red and Heavy, heavy and red. Nothing.

Then in a flash of inspiration it came to me -

You've bought a housebrick!

I am amazed by own genius at times. I can hardly wait for the pictures.

Regards

Chas
