Help me find these tiles please..!

[sw15mum]

Does anyone know what the name is for these tiles (pic attached) that go over a step? Googling every term I can think of isn't helping...thanks!

Kerb stones?
Block paving edgers?

(Don't know - just guessing!)

Kerb stone edging.

Have actually googled that and got right things. These are actual blocks though so do you realise that? They don't go over something else, they are an actual block/stone. (Apologies if you do know that!)

Is it a bullnose brick?

They are referred to as 'blue bricks' you will find them under that

Thanks all! And know I didn't know they were blocks so special thanks for that info!
