About two models of HP mini covers:
This New Discbound HP Mini cover has the same internal layout as the Discbound Half Letter cover.
It still fits the 1.25/32mm disc as perfectly as the Original HP Mini cover. But at the same time we have also increased the size of this new discbound HP mini cover to make it fit 1.5/38mm disc as well, something the original HP mini cover could not do, which is great for people who like to use larger discs.
Original hp mini cover open size: 33x20 cm closure size ：16.3x20 cm
Discbound hp mini cover open size: 35x20.5 cm closure size: 17.5x20.5 cm
