Membrane boxes use a highly elastic transparent membrane to suspend devices between the upper and lower films inside a clear box. Thanks to their elasticity and transparency, even irregular or non-flat components are held securely while remaining fully visible from all angles. Available in M1 (hinge-less) and M2 (hinged) series, they are reusable and support custom logos, anti-static materials, and hinge colors—ideal for optics, prisms, crystals, test sockets, jewelry, dentures, and watch displays.
