During various tests of our trays, we found out that it would be a good idea to reduce the size of their edge a bit so that they fit all boxes, not just 18xx games.
That is why the new series of trays, which was recently produced for us, has 1mm smaller edge on each side. In total, therefore they are 2mm smaller along their length and 2mm smaller along their width. Their current sizes are: 288mm x 212mm.
However, a certain number of high trays (15mm) from the first production series, i.e. a bit larger (290mm x 214mm), remained in our warehouse, so we decided to put them on a discount and while stocks last, you can buy them 20% cheaper.
