This block box is part plastic and part wood. It stands approximately 7.75” X 4.5” X 5.25”. There’s a turning cog on the front. An up-and-down slider on the back. All of the edges are smooth.
The only thing I’m not super impressed with is the lid. I wish it had been a simple hinged lid with latch. . . but. . it’s not. The lid is wood and removable. There are two tiny plastic clips on each side. . . but. . they really don’t hold the lid in place. I pulled them out a little, to see if that would help. . . but. . .instead of not holding the lid in. . . They held the lid in and would not let it go. So I had to push them back.
