These are bunny stamps from Mama Elephant. Of course, they have other stamp kits - an incredible number, actually, with many different themes - but this is a bunny blog.
This particular kit ($15) contains 20 stamps (16 images and 4 sentiments). The stamps are not wood but clear, so you can stamp the rabbit and then add whatever "adornments" you want. They also have a wide selection of ink colors.
I went to order the bunnies but they were sold out! However, you can enter your email address so that you are notified when they are back in stock. They were on the Today Show this morning and if you enter the code TODAYSHOW, you get 10% off your entire purchase!
Oh, and here's their Facebook page.
P.S. If people want to buy kids a bunny for Easter - this is the bunny they should get to play with, not a live one!
