I've been trying to remember the name of this toy for ages, I used to have it when I was little. Then when I was browsing one of my favourite shops, Present & Correct I saw it as a prop in the background for one of their items.
They were very kind to answer my excited email and help me out. It's called Octons. Apart from the shape it's the translucency I like (see bowls below). You can buy it today but they've changed it. IT'S NOT TRANSLUCENT ANYMORE! (Ahem) taking away most of it's beauty.
Here's an original one from ebay a couple of weeks ago. You could make a lovely sculpture with it and pop it by the window. Anyway, please give me the nod if you spot one anywhere. Nudge nudge, wink wink, say no more.
Have a lovely weekend all. Hoping for sunshine. x
