We have exactly the same slide boxes of Hama for decades home for our old slides and the difference in quality for this new product is enormous. The 30 years heep boxes look still "new", as the newly supplied by Amazon slide boxes. Hama seems to have changed, the manufacturer or very to use inferior materials. The plastic is stained and looks dirty looking and can not clean themselves. The closure would hardly think. Overall, I am very unhappy. The slipcase look as if they would be year long in a wet basement rots. For the price an impertinence.
