Little Darlings Cutie Pies Unmounted Rubber Stamp-Sitting Pretty

I was so excited to get these. i am a fairly new stamper and have had the most fantastic experience with all of the clear, rubbermounted as well as wood stamps that I have been making cards with up until this time. Never have I had a problem with stamps. I got these a few days ago and immedietely inked them up and the stamps fall off the acrylic blocks as you turn over the blocks to position them. Totally useless. So upset. How could this be so poorly manufactured. Returning. DO NOT PURCHASE!

Beautiful little stamp - cant wait to use it. Don't think I have used any of their products before so this will open up my list of choices. Quick delivery, well packaged. Thank you
