2GR-Ferrara Siphon - 200cc - 7oz|
2GR Plastic bird waterer from Italy - 2" diameter x 5.25" high with a long lip. Easy on and off and holds almost 7 ounces, 200 cc. Available in Blue and Clear. Fits 1/2" spaced cage bars. Slightly different the STA water tubes but holds the same amount. I love these water bottles and use them with my own flock of Lady Gouldian Finches.
