This product is fantastic. Looks professional and scores high on practicality. Disk posts in a secure card wallet - unfortunately there's no thin plastic window (personally I feel this would improve the overall feel of the item?) Once customer has received their disc, you tear of the insert which allows you to keep the disk in a folder or disc flip container. I have taken to printing stickers to attach to the insert - business name number etc.
Cons - they are slightly fragile & could tear after repeated opening closing.
As long as you can resist the need to keep opening the card wallet (ie prep your contents & put them all in together) you should find these trouble free. I would definitely recommend them.
