Why don't you put a piece of disused photographic film (neg) inside?

A lot of people make their own feeders from old film. This way you can
have
them the way you want them.

I used to make my own feeders, partly because I like to make my own tackle
and partly because commercial feeders are expensive and not always the right
for the job.

For open end I used a sheet of clear plastic ("borrowed" from the binding
room at work!) and lead flashing (B&Q), 2" of Power Gum and a snap swivel.

Maggot feeders were made using old photographic film casings (smile nicely
at the nice lady at your local Boots!) and the same lead flashing, gum,
swivels. I found that the holes are best drilled at 6mm and then the rough
edges smoothed over with a soldering iron...

£15 of materials is enough to make enough feeders to last 5 years -for me
anyway!
