OMG freaking cute! LOL. The kitten freaking out upon seeing its first butterfly is just priceless. A great design from a Society6 designer. It's so much fun to shop there and see stuff that comes from the fringes of great creative design minds. You can read all the info about the materials in the last photo showing the inside tag with that info. It measures approximately 9 1/2 in by 5 1/2 in. The zipper goes all the way to the last two teeth and stops there but that is because it is the nature of the design. It does not leave any opening large enough for anything to spill out. That's simply because there is a thick inseam there. I mention it because it is new to me since I do not carry these around and have never examined them up close. Maybe a lady would know that off the top of her head but it looked surprising to me at first. See my last photo and you will see anyone would consider that shut tight. Unless you plan on filling it with water and carrying it around like a water balloon LOL. This may be the sort of design that is no longer available anywhere if the designer no longer has her or his account going there. I did an image search and it seems to be exquisitely rare. From a smoke-free home. It's really cute enough to just display as art rather than use.
