After each handwritten letter, we often burn wax to seal the letter, because the letter feels more complete. The wax and seal that Cabin uses belongs to Kalêndar, a friend from Hanoi that we have known for a long time. Founded in early 2019, Kalêndar is a studio specializing in handmade wax and seal making. Their seals and waxes are crafted and come in a variety of options, so you can mix and match easily, from choosing a wax color to blend to a variety of seal textures. In addition, Kalêndar also has lovely envelopes, helping your letter when sent will be more complete.
