Primers and ultra-bonds for nails

Here are collected the liquids of the preparation stage — primers, ultra-bonds, and dehydrators — 16 items from ten brands in packagings from 8 to 15 ml. Half of the confusion is removed by one observation: in this catalog, "ultra-bond" and "acid-free primer" denote the same thing, and some manufacturers write both words in a single name. There are four acidic formulas here, and their names always contain Acid or "acidic".
