I have. They are awesome. No, they don't individually cut out the decals. At first I didn't like it, but as I got some good knives and scissors, I actually like it better than the ones than come in kits. They are thinner as well I think, so they go on better. There isn't a lot of film so you don't get that murky white stuff you do from production decals. And his decals come with many versions and are REALLY detailed (each lifeboat has its own miniature number) Here are some pics of two ships I did with custom JTG. One is the West Point and the other is the Winfield Hancock. The decals REALLY bring out the detail.
If you spray the model with gloss coat the decals go on REALLY smooth, then overspray it with dull and they are “Locked In” Good luck, and once you go with JTG, you’ll never go back.
