Coming back into the hobby after a decade plus hiatus has been an eye-opener for me. The quality of kits has gone up, and 3D printing has created a large market of aftermarket items. These items can make a kit look more accurate, or enhance the quality of the display.
The Aires USAF/USMC land based wooden wheel chock with nylon rope falls into the enhance the quality of your display category.
You get 6 chocks per set, 4 large chocks (presumably for main gear), and two smaller (nose gear) chocks. A segment of thread (simulating nylon rope) also comes in the package.
The packaging is nice. The chocks are in a clear, re-sealable bag that has an instruction sheet inside.
Preparation and assembly is straight forward, I paint the chocks, drill/clean the hole for the nylon rope (thread); sand a small strip where I will apply glue, and then cut them off the sprue as needed.
