[ Delivery to Fred and George Weasley ]
This box has been cold-packed to preserve freshness. The contents of it appear to be the sort of jello one would find at picnics, with the things floating in it. There is both a red one and a green one. Attached is a note:
Apologies on not making your barbecue, it sounds like it was quite an event. A previous engagement I had went badly, and I couldn't make it. I'm not sure you would have missed my company, but I thought you might miss the jello I promised to bring.
I thought I could at least send you some of that. I hope you enjoy it.
