Query: Very shoddy--didn't last 6 months!

Though pretty, these flip flops were very poorly made. The sequins started to come off immediately (some had already come off in the box when it arrived; a few more showed up on the floor each week. The stem that divides the big toe from the others started to fall apart to the point that the flip flops became completely unusable after 6 months. And this was only with moderate wear, primarily around the house! Avoid this product!
