Thank you very much for looking at my items among so many! (*^^*) Twisting Foraging Toy Set - Bird Toy - High Difficulty Level ⭐⭐ * For cage attachment There is one 3mm hole and one 4mm hole. * It's easier to twist now, but the difficulty level is still high (((^_^;) ✨✨There are videos on Instagram of birds playing with it skillfully! I also have other recommended bird toys for sale!! If you press ←, you will see my product list (^3^)/ Please take a look m(_ _)m * The photos are examples. I will send you one made in a similar style. Simple assembly is required by just inserting the parts. Recommended for parrots who like foraging! * I have made one 3mm hole and one 4mm hole! Put treats or favorite toys inside the foraging toy and play! I strive to make each item carefully to meet your expectations. * I have chamfered and sanded the corners as much as possible. * The photos with parrots are for reference. I have received good reviews, but these are handmade items. I am not a professional (^_^;) There may be cracks or scratches. Please only purchase if you understand this.
