I've been looking for some small parts trays at a reasonable price that would fit Lista, Stanley-Vidmar, etc type cabinets. Found these Tekton blow molded plastic trays for $7ea. Fairly thin plastic but fine for my use. 13.5" x 10.25" 4, 7, 8 or 12 compartment. I think they have a larger size too. Got plenty of the metal dividers and I use those too but wanted something different.
