None that I noticed after taking them out of the wash but they are not as nice an clear with dark coloring as they were when I first took them out of the packaging - they have faded. My husband has allergies and since I had one premie twin (and one regular weight) I washed everything before giving it to her as an infant and recommend doing this. I bought a new shirt at Old Navy about 1 month after being home and wore it without washing it first and both babies got angry.
Sure, I can ship more than one auction together. I just have a lot of stuff because I am like the "old woman in the shoe" so I didn't think that anyone would need more than one of these toys.
