Collectors judge the quality of current Montblanc leather goods differently: some see a quality loss compared with older editions; others still hold today's leather goods to be high-quality and market-leading, especially compared with the competition. Particularly older cases from the 1950s are valued by some for size, haptics and cut, while others see nothing special in them. Montblanc's repair and exchange service is regardless rated as accommodating and fast. On textile-coated pieces like the Nightflight key case (silk-cotton mix with impregnation), unraveled seams have been reported repeatedly as a typical wear problem.
