Line them with tissue paper to hold a favor. Fill with Jordan Almonds, mints, candies, lavender, coffee, tea or other special item inside. Apply self-sticking circles to lid and printed with names, celebration date, or an embellishment. They can be painted or decoupaged. (See photo suggestion.)
These are also used as high-quality candle tins, so they have a varnish on the inside to keep it from discolation. Leakproof.
