INVIS opens up entirely new possibilities in furniture making, kitchen construction, exhibit booths and interior architecture - without altering appearance. INVIS is always invisible. Covers are a thing of the past. A delight for the eye. INVIS introduces a new quality in furniture making, with mobility in furniture assembly now possible. Where previously finished and bulky items had to be transported, INVIS enables a knock-down advantage for on site assembly to save time and transportation costs. INVIS also helps saving time when gluing is required. Instead of costly clamping devices INVIS can also be used as a "hidden thumbscrew". Use INVIS for an elegant appearance in display case construction and service-friendly frame design.
