Designed specifically for the Teenage Engineering OP series, this dedicated black Teenage Engineering OP case is designed with a tear and abrasion-resistant shell fabric. An EVA panel on its front fits to fit OP series knobs and protect from damage while a Japanese, water-repellant nylon lines it. Its hardware is designed from a premium, custom-designed aluminum alloy that shields it from impacts. Along with this quality design, a secure front pocket fits cables and other accessories while hook-and-loop straps on the back allow for multiple uses. This case fits the OP-XY, OP-1 field, and the original OP-1 series synthesizers.
