Thank you very much for looking at my items among so many others (*^^*) There are two holes, one 3mm and one 4mm. * It has become easier to turn, but the difficulty level is high (((^_^;) ✨✨There is a video on Instagram of a bird playing with it skillfully^^ * The photos are examples. We will ship items made with a similar feel. Simple assembly by just inserting is required. Recommended for parrots that like foraging^^ Please put treats or favorite toys inside the foraging toy and play with it! I strive to create each item carefully to meet your expectations. * Chamfering and sanding of corners have been done as much as possible. * The photos with parrots are for reference. While I receive good reviews, these are handmade items. I am not a professional (^_^;) There may be cracks or scratches. Please only purchase if you understand this.
