Dioramas, displays, model car, kits, etc. all need accessories to enhance your scale cars and trucks when displaying them. You have to have accessories or it doesn’t look real, look at any shop, garage, building, etc. they all have stuff in them and/or around them.
I get most of my accessories from Collectable Diecast .com they are one of the best companies I have ever dealt with. They also are knowledgeable and have the products right in their warehouse so the items ship fast.
I have included them as an affiliate of How To Make A Diorama .com because of their great service. The following link is an affiliate link which means you pay exactly the same as if you went directly to them. The only difference is I receive a few cents by you going through this link which helps keep the How To Make A Diorama .com site running, which in turn helps everyone who stops here along their way building dioramas.
When you get to the site there are many companies and products on the site, if you are looking for accessories for your dioramas they are under Unique Replicas and American Diorama they may also be in other areas so look around their site. The pictures displayed here are all 1:24th scale, they also have 1:18 scale and a few 1:64 and 1:48 hopefully you will find something to enhance your diorama builds or displays.
