I'm assuming its the Wall Lantern you can buy from your estate maidservant/butler now (along with many many many many other old furnishings that you used to have to craft). 3000 gil and easily desynthed with BSM. Still I don't see who would buy literally thousands (tens of thousands?) of these in order to flood the market with stacks upon stacks of Frosted Glass Lenses. They're good, but they're not THAT good, and the lantern will long since be useless for desynth leveling before you even get a couple stacks of Frosted Glass Lenses. It's still baffling to see that many frosted glass lenses from one person no matter what the method of acquisition. Nobody wants 99 Frosted Glass Lenses.
