Mine arrive in a mailer tube, I then tip them out into a 30L tub, and separate them into 70 -80 cricket batches and they go into old Piscus/ BioLabs cricket tubs with some fresh carrot, some adult beardie pellets in each) and I keep these 9 - 12 tubs in a cardboard box , layers of 4 separate by egg holders (for good air flow).
Works for me.
I always manage to loose a few on the transfer ,and when getting the meals ready. No problem, we have a friendly wild water skink who visits inside and I suspect she catches most the rogues and eats them (she has really beefed up since she started visiting us).
