We need some more (a lot more) of the little black metal clips like the one shown here.
72 Nickerson Rd

It might be a while before we can have these made commercially so salvage and re-use is in order. The clips come right off old Pol sheet films with the application of heat - like a very hot hair dryer or a heat gun. Be careful if you do this so you don't get burned. Otherwise the entire sheet after processing can be sent. Old, expired, dried-out, exposed, surplus or just lying around, we need them now!
And thanks to those who have already sent some.
