Stainless steel is stronger and longer-lasting than aluminum and is recommended for all medium and large hookbills.
These bands are made for hookbills and so have thick walls to keep them from getting crushed by powerful beaks. Bands marked "Thin-Wall" are slightly cheaper and are suitable for smaller birds or birds with less powerful beaks, such as poultry and waterfowl.
Some bands specify whether they are "Tall" or "Short". Some breeders prefer short bands, especially for birds with stubby legs. Others may prefer tall bands because they are easier to read and can accommodate two lines of text. Unless otherwise noted, all sizes 6.5mm and under are short and all sizes 12mm and larger are tall.
