@lizortiz1989, I do believe they come in all sizes and if you go on amazon you can type in thermos baby bottles and it pops right up, I paid 10 bucks for mine
The only color i see them in are green and pink im not sure if they come in one more color
I was thinking of getting those too but decided not to and instead I got glass baby bottles and a few thermos baby bottles
Yes I got 3 glass Gerber ones with the pink sleeves I love the glass ones except for when ....u know lol
