Butterfly clip for knitting

[Dutchoma]

Several years ago I had about six butterfly clips as a free gift with a magazine, can't remember which one. Bright green, two little prongs on a clip, incredibly handy for sewing up. I'm down to three and can't find a supply anywhere.
Does anybody know what I am talking about and where I could find some more?

There's a pack on eBay for £5.99 with free postage. Search 'CLOVER WONDER CLIPS' and scroll down because there's quite a few with expensive postage rates before you get to them

Now they are all coming out of the woodwork.

But not quite sure they are the same clips. They could be, ut you can't quite see them individually.

With thanks to BigBoobiedBertha for the knitting clips that arrived today

No problem. Glad they are going to a good home.
