Every year, Caran d’Ache creates a new Ecridor Eclat Winter Edition. The latest is the Sonate d’hiver collection, available in September. The hexagonal ballpoint pen ($365) is platinum-coated silver plate, accented with 57 Swarovski crystals—eight black and 49 white. The crystals conjure notes on a swirling engraved stave to create a lovely winter sonata. The pen is fit with Caran d'Ache’s Goliath cartridge for a long write out, and it comes in a black velvet pouch accented with yet another Swarovski crystal.
