Sorry, sure this has been done many times before but I can't find it via a search.

Can anyone recommend a good source of sturdy 45rpm-sized cardboard mailers/boxes?

Agree with Smithy - this guy here ^^ is the best - ditched Covers33 a while back - too expensive and their products just keep getting thinner and thinner...

I'd stick to the fold up cruciform type tbh, they're a little more expensive but offer much more protection than the envelope type mailer, the other half had two 45's arrive yesterday in one of the envelope type mailers, both 45's were damaged when opened, it's a real shame cos it's not always about the money lost but the the fact that those records are gone forever

I usually send in big fold up boxes packed with loads of bubble wrap, but where I'm flogging cheaper records it seems a bit OTT (though I do take your point about damaged 45s, it is heartbreaking).

Thanks everyone - I'll try Pete's recommendation on the basis of Mark's endorsement. Thanks again.
