The listing, 2 Sleep Sacks Calvin Klein and Carter's Baby - Size 0-3 Months has ended.
The yellow one has the attached scratch protectors that go over baby's hands. I have no idea what they are called, I just know they are to protect the baby from scratching his/herself as well as you. I use them to keep my daughter's hands warm, I guess they are versatile :) She never wears her clothes more than once so these are in very great condition, practically new. My home is smoke free. The Calvin Klein one is pink, not white. The picture just makes it look that way
