Wax Furnace and Spoon
After trying all the methods for melting wax onto an envelope, we at Postscript have fallen head over heels in love with this tool. Simply place the base over a tea light and put a wax pebble or a chunk of a wax stick into the spoon, and let it melt hands-free while you address your envelope and affix the perfect stamps. Added bonus? It looks gorgeous sitting on your desk even when it's not in use.
