G'day Olivia,

The bite valves are a soft rubbery like plastic. The replacements are the same as the bite valves on the Camelbak Kids Bottle. 

G'day Andrea,

Thanks for your enquiry! We don't have a clear date for delivery with our supplier, I'm sorry to say. They sell out faster than we can get them in! You can click the "notify me" button so we'll email you once stock arrives but please note we do have a large number of allocated orders to other customers so it may be best to place a pre-order, as you may miss out. 

G'day Kerin,

The Camelbak Eddy Kids Bottle Bite Valves come in an assorted 4 pack and I've checked our stock and they're all the same colour combination as the image.
