hey guys my brothers daughter was around with him last weekend and she has pulled the as1698 sticker off of my helmets :( and now they ar "illegal" due to the fact the stickers are gone, how can I get replacement stickers as they are basically new and I really don't feel like throwing out two good helmets

I think you can buy them online from 'somewhere' but thats not halal at all.
 
You could try the manufacturer. If they are normal looking helmets I doubt you'd get done, not impossible but not very likely.

They would still have the AS label stitched inside wouldn't they?
