John,

I sent a package of 5 chips earlier this week to another collector as my end of a trade. I cut up an old 30-slot 8.5" x 11" plastic page into a group of 5 slots. Each slot firmly holds the chip so that they do not flop around in the envelope. The chips were then put in a bubble envelope. The envelope was stapled closed and then secured with packaging tape. According to my receipt from the post office, the package weighed 2.5 oz and the postage was 77 cents.
