From the release:
We have five new vehicle decal sheets for you this week! These high quality waterslide transfers are designed to go with our 1:56 scale Bolt Action vehicles.
These decals will finish your vehicles off perfectly and they are very easy to apply. Simply cut out the desired decal, leave it in a dish of lukewarm water for a few seconds and then slide it off the backing paper and into place. Using a clean paintbrush will help in the positioning of your decals as well as making sure they are free of trapped air bubbles.
