This wooden flatpack kit allows you to fit pieces together to make your own custom ketchup spin top! Get creative coloring the grid of bottles using markers, highlighters or colored pencils - we don't recommend crayons, but pretty much anything else will do. Unassembled, the kit measures 4 1/2" x 5 3/4", and arrives in a clear plastic sleeve with an instruction sheet. To ensure the steadiest spin, we suggest using a very small dab of glue to hold your top together. Our record is 25 seconds. How long can your top spin?
