Screws | One faint streak / vinta is acceptable (visible at a distance of 1 m). The strip should not delimit the product or disturb its appearance. The standard minimum glass thickness of the products is 1 mm. If the customer requests products with a glass thickness below 1 mm, the glass factory can produce them, but without guarantee. It should also be noted that the correct blowing and shaping technique cannot be followed when the glass is less than 1 mm thick. Because the enamel is not properly processed, the structure of the glass can be visible and thus visible imperfections such as vins, glass translations or fine mead (hairline). We would like to draw attention to this fact before starting the production of such an order. | ||

NOTES:
Decorated products (with gold, platinum, or spray-painted) must not be washed in a dishwasher. All decorated products must be stored in dry conditions (especially gold, as it can corrode if left in moisture). Prices are calculated based on quality standards, and all complaints under these standards are considered unjustified.
Other quality options are available according to customer requests, with adjusted pricing.
