Although natural and very pretty, some had holes in the middle
Although natural and very pretty, some had holes in the middle, not a big deal as it still keeps the glass of the table.  The clear rubber sticky feet you put on the bottom so it doesn't scratch the table are small and great size.  Unfortunately there weren't nearly enough for me to use so I had to go to the store and find my own (but couldn't find ones of the same size).
