Making the Finn or Night Sword

Making Product
Making Product

Adventure Time Finn or Night Sword costume replicas are durable and lightweight.  Hand crafted from layered ¼” thick wood, providing structure and remarkable detail to create a replica as close to the original source as possible.  Specifically we sand, prime, paint, glue and micro nail each layer together creating a strong and durable fully immersive cosplay accessory.  Subsequently creating a highly decorated replica piece made for the imagination.  However, we do not encourage actual LARPing as paint and more delicate sections are prone to damage on collisions.
