This Milk Powder Dispenser by Nuby is fast and convenient. It is divided into three sections to help with pre-measuring milk powder for you.
The small-cap is attached so it doesn't get lost or misplaced. The larger lid securely snaps on, but conveniently slides around the top for easier and less mess access to each compartment.
Note: the Milk Powder Dispenser is perfectly sized for travel. Plus, it's BPA Free.
