Tips on sending records.

Placing a record(s) onto cushion or bubble-filled envelop will mean that the package will be traveling together with letters and not parcels. Even If you place your record onto the cardboard mailer I would still recommend placing the same box onto envelop. This experience shared with me FedEx clerk.
Thanks for the tipo. But how about UPS, the champion in wrecking shipments (my experience)?
No-UPS period.
