Size: [Card] 10 x 10 cm, [Envelope] 11.2 x 11.2 cm Set includes: 12 types as shown in the image (each card + envelope) A greeting card featuring animals that pop out from the cover to the inside. The happy, smiling animals are impressive and make you smile too. Part of the cover pops out. When opened, animals in various poses pop out with positive messages like "Smile!" and "Happy!". This is a set of 2. I bought these but didn't use them, so I'm selling them. I look forward to your purchase if you understand that these have been stored at home.
