Most of our Hobby Gear line is 1:24 scale. We don't list the scale because the accessories will work with other scales such as 1:18 and 1:32. Since many items vary in real life, for example large and small toolboxes, we do not want to discourage using the accessories on similar scales. We do our best to put actual dimensions for each item (please check items in 17xxx series) so you can determine if they will work for which ever scale you are working with. We appreciate all comments and concerns. Thank you.
