Allergy-free treats for school (birthday)

[SakuraM]

Hello,
Could anyone please give me some ideas about allergy-free treats to take to DD's class on her birthday, just to mark the day, as we were advised against cakes. Ideally everybody will be able to partake regardless of allergies, religion, etc. Nothing home-made I'm afraid.
Thanks!

Mini bags of haribo or skittles or other sugar based sweet. Means dairy free is catered for too

Gummy lollies might not work for some religions. We find clear lollipops are fairly safe for most people. Some may have issues with colourings tho. Send in the packaging and let the teacher allocate them, they'll know who can have what.

Thanks for the suggestions!

I am taking cadbury's buttons and Asda's dairy free buttons for the kids who can't have milk. There are no other allergens in them (and they don't say may contain nuts or soya or any such)
