Reusable Swim diapers

Lot of swim diapers. First 2 are AlvaBaby brand. They have several sets of buttons for precise sizing. They do not have a specific size listed inside, but I used them for my 18 month old. The yellow and purple are iPlay brand. Size medium/18 months. Button closure on one size. The pink is Swim School. It does not have a button closure. Size L/18 months.
