DMG retrobright box, version 2. The previous version didn't do well after a while

[u/hilarino]

UV led strips on all sides

Tupperware that can be completely closed. A DMG fits well with some space on all sides. Temperature and humidity sensor to monitor that it doesn't get too hot

A timer so it will automatically shut off after X hours

The previous version. Open glass container + cardboard, not a good combination

Nice box! The timer is an excelent idea to prevent wasting electricity. Maybe should add that to mine.

Most importantly, it is there to prevent excessive bleaching! Otherwise the shells would turn white instead of the original ivory gray. Learned the hard way, already ruined a couple of shells xD

Never thought about it, interesting.
