The air-tight capsules and the display tray were great. Sadly, the display tray did not fit inside my display case, and I was forced to send it back. (I did get a refund.) I am suggesting that you tell the supplier to cut off the extra wood underneath the tray. That extra length is unnecessary and is the reason I could not display my coins properly. Other than that, it was a great experience, and I will use air-tites.com again.
