After a couple of moves, I started to consider getting more sleeves for CDs and LPs. I didn't care for this much previously, but it's annoying trying to pack all digipaks into moving boxes without getting them all scuffed up during the move. CDs in regular jewel cases = God-tier packaging that you can just throw into a pile and no problems!
Mostly I'm in a need for digipak sleeves. The digipaks F&V uses seem to be some standard size. They are not the biggest issue because the glossy surface is durable, but matte finished and more cardboard-like tend to get in worse shape quickly. How about bulkier and weirder sizes? Like Bomb the Daynursery 3xCD, Macronympha's Whorechestra or Mangled Clit's Erotakill.
Sarvilevyt used to sell some great LP sleeves years ago, not sure what brand they were, but they were clear and thin. I could also buy more of these if still sold somewhere.
