I got a set of 20th Anniversary Resorts AC chips in a special book-shaped holder from ebay. The seller put plenty of padding in, but not enough to keep the book from opening. When I got the box, every chip had had fallen out and were all rattling around on the bottom. Impressive given how tight a fit they are. Luckily, no chips in the edges. I told the seller that the best feedback I could give was neutral due to the shipping method and he got really angry. Ended up leaving no feedback at all.
