Have used both the bamboo and plastic type..like both. Some think the bamboo gets contaminated with the chemicals, but to be honest, I just wash mine and never leave the tongs in the tray..just set the on a corner. The plastic ones are nice because the ends are at an angle which is nice to slip under the print..and then I just left the print out ... Have seen the metal (SS) and they are nice and are suppose to release so that you do not put to much pressure on the print. Think as others have pointed out got to Calumet or Freestyle and order a good set ... mine are labeled for D eveloper, S top, F ix, T oner...to avoid any cross contamination. May not need to, just old habits.
Reminds me, need to get a couple of new sets just to have...if these don't work, try looking in a hardware store or kitchen store..may find a good substitute you can tell us about.
Good luck..
