I'm looking for darvic/salbex white sheet (0.5 thickness) to flag and attach geolocators on shorebirds in China. But unfortunately, BTO ran out of white that I need and another supplier from the UK only sell it in big bulk. Also, our ringing centre does not provide leg flag for shorebirds. I wonder is there any other places that I can get these materials in a small quantity and could ship them quickly and internationally?

Thanks a lot!
