This is a set of ball-shaped foraging toys (3 balls) and a dedicated box. The mechanism allows food to come out little by little as the balls are rolled around♪ 【Ball Set】 3.2 cm balls. Hole sizes: ・4 mm (1 hole) ・6 mm (1 hole) ・6 mm (2 holes) You will receive one of each of the above patterns, for a total of 3 balls. Please use them according to the size of the seeds and your preference for how easily they come out♪ Sunflower seeds will not pass through the holes. The 6 mm (2-hole) ball is easiest to start with, as the food comes out easily. Your bird will begin to understand how to get the food. ＊About opening and closing the balls: You can open them by gently squeezing the mouth of the ball with your fingers. Please be careful not to use too much force, as this may damage the ball. ●Holes are made by drilling. There may be some burrs, but we will try to remove them as cleanly as possible. Please understand. ●Additional ball purchases are possible depending on stock availability. Please inquire separately. 【Box】 Size (excluding screws) Width: Approximately 16 cm Depth: Approximately 14 cm Height: Approximately 3 cm The bottom plate is slide-out for easy cleaning♪ The small screws that secure the bottom plate are made of safe stainless steel. I use these for my own birds, so I am careful about metal poisoning. ●This will be shipped in a Mercari-specific box.
