Our G scale Scenic Accents are 1:22 scale.
They are made of ABS lightweight plastic, which is a plastic resin material.
We recommend the Scenic Accents Glue (A198) if you want to be able to reposition items without having to reapply glue each time. You can also use our Hob-E-Tac (S195) with somewhat the same results. For a more permanent placement you can use our Scenic Glue (S190). For easy placement, use our Gentle Grips (A200) which is a unique tweezer used for positioning small items.
