These items are useless.  They are literally paper thin and utterly useless.  I cannot imaging any situation where this item would be useful. Place a planter on this "Saucer" and it will likely crack/split as mine did.  Got this as an add-on item at a cost of $3.08.  It would not have been worth the $.08.  Complete waste of time and money.  And in addition, ordered 3 of these, each shipped individually in a huge box.  WHAT A WASTE AMAZON.  1 star only since you can't go any lower.
