At ZIGHT we understand the importance of a proper packaging in the tube.

All tubes are packaged individually inside a plastic bad, which prevents scratches and glass spill in case of breakage. All tubes are also packed inside a box, with protective foam and cartons between each tube.

A standard box consists of 6 tubes in each layer (the base), which are placed with protection cartons be-tween each tube, and 2 rows which go above the base, also with protecting cartons between each layer of tubes.

In total, each standard box has 12 tubes properly protected in order to be shipped.

Special packaging instructions in terms of packaging material and quantity are available upon request.
