SA fly boxes are very well made and these inserts are a real bargain. They fit the standard size System X boxes. These boxes work well, but you have to squeeze them to create a vacuum inside so that they become waterproof. If not squeezed they leak.

I purchased a number of these waterproof fly boxes through STP a while back. When I saw the extra inserts I decided it would be a great way to better organize all the flies I have accumulated. I like the way you can pack the flies into these boxes/inserts. If you get the inserts, be sure to get the "suitcase" organizer, which holds four of these inserts, to help manage them. If you don't have the original fly boxes these inserts go into, you could still use the suitcase, but it is not waterproof so you may want to think how you would use these.
