I received these yesterday, 5 days faster than estimated shipping date (gotta love that).
They seem to be quite sturdy and I'm hoping they'll last a while.  They have a little black pad foam on the back so they don't scratch a table surface and seem to be sturdy enough to hold a decent size purse.  Since they are going to be party favors I haven't actually taken them all out to use, but so far, I'm pleased!
