I got these at AC Moore, but Michaels also carriers them. The Deco Art website has a dealer listing to find a place near you. They should be near the paint section in any craft store if they have them.
Here’s a pic of the two side by side. I bought both the wide tip and the small one which would be good for hard to reach spots or very detailed work.
The claws and touchups are unsealed at the moment. I wasn’t impressed with the selection of sealants they had in-store so I’m browsing online for a few good ones.
