Bark creates phone cases made from sustainable 100% Swedish hardwood, sourced from trees felled due to necessary forest management in parks and green areas. Each case is milled from a single piece of wood ensuring the natural wood grain is visible and no two cases are identical. The design includes reinforced edges and the wood itself offers natural protection against impacts and drops. The company emphasizes environmental responsibility (it keeps away from plastic and utilizes locally available resources instead) and traceability (by providing information about the specific location where the tree used for the case was originally located).
