These are made for glitter but are so much more useful.
My group makes hundreds of cards each year for church fundraising purposes. For economic reasons we use common white glue for most adhesive purposes. We use one ounce bottles which we fill and refill from the larger container. It was always messy until I found these funnels!
I bought two sets and plan to get a set for everyone in the group.
These little funnels are wonderful to help you put the extra glitter back into its holder. It helps you contain, (if you can contain glitter) the glitter to help so it doesn't scatter even further. I would buy these again.
