I use a lot of cardstock and foamcore terrain on my tabletops, but I really like resin for scenics and props because of its wieght and 3D detail. I thus have a lot of little fiddly resin bits in my collection, so I decided to write reviews of some of my favorites. This set of crates from longtime resin casters Armorcast can find a use in almost an genre from pulp to WWII to espionage to SciFi and beyond. They make great cover or mission objectives, they paint up quickly and they look good on the table. Overall a pretty useful bit of kit. Check out the link for the full review and pics.
