Finally I have uploaded Sand In Boxes to Bandcamp. You can now download it for 3 euro (or more).
For digital purchase follow this link to bandcamp: http://orphax.bandcamp.com/album/sand-in-boxes
I also have the two last copies of the second edition CD-R’s available. If you are interested just send an email to firstname.lastname@example.org (they are now 6 euro incl. shipping because sadly enough the slimcases got broken).
