Our empty trays are made of ultra-light and dimensionally stable foam.

Basically, the trays are available in 3 different heights:
- 3 cm for prescription frames
- 4 cm for sunglasses and large prescription frames
- 5 cm for large sunglasses

The trays are fitted with spectacle inserts (inlays), which are also available in different sizes. This gives you greater flexibility than with conventional trays. You need to keep fewer trays in stock, which saves money and space.
