I use these thicker wooden shims when I need to level an uneven board. Photos are attached. I couldn't find the type of pads I was looking for in the big store so I ordered them here at Revain. I read someone claiming their pads aren't cedar. Although it doesn't matter for my use as I only use them for real shimming. I think it's great that you can get a lot of wooden spacers for little money. They should last me for years as I will be reusing most pads rather than throwing them away after each use. This is exactly what I was looking for. 5 Stars
