I need empty Wrapping Paper Tubes

I need several wrapping-paper tubes (the empty cores from the inside of the roll) for a program I'm leading this Sunday. Luckily, it seems like a likely time of year for my friends to have those. Please let me know if you do!

Alternately, if you have any Nerf bats, or short extra-padded boffing weapons you wouldn't mind lending to grade schoolers, those would work great, too.

Thanks!
