Lego party bag fillers - what would you chose?

[IcingandSlicing]

Hello I have seen people putting those small bags of Lego toys as vehicles, planes etc. in party bags but where do you buy these from and how much they cost?
What else could be a good (i e inexpensive) party bag filler for a Lego party?

Thank you for all suggestions!

In home bargains recently they had brilliant Lego sticker books with a Lego figure on the front 69p

Search Lego party bag fillers on ebay, for both the bags of lego and other themed ideas like bookmarks, keyrings and stickers. But that Home Bargains one sounds like a good tip.

Lego Mixels are good for party bags.

The little mini figures - around £2 each - available at WH Smith etc etc. I think with a small packed of sweets and a piece of (Lego-themed) cake, this is plenty. I did this for my Lego-mad son's birthday and they kids loved them.

Thank you everyone! Great ideas!
Celeriacacaca can I ask what kind of entertainment did you provide for the party? Was the entertainment Lego-themed as well? Still thinking about it ...

Thank you ShowMeTheWonder! I haven't seen Lego chocolate moulds but will look for them on ebay, sounds like an absolutely brilliant idea!
