Excellent kit with AN MS quality rings. Don’t use the cheaper kit for aircraft. Would love Aircraft Spruce to make another kit with same sizes but smaller diameter widths, such as 014, when kit has #14, etc. This is a very big MISSING item in their inventory.

Great value for the money and its nice to have the organizer case. It may not be everything you need however. For example, you might need the smaller width in some sizes. Also consider whether you can use a substantial number of them before they expire.
