Made with high-quality 2mm thick felt (※very rare sturdy type on the market) 5 pieces for 1000 yen [Product Description] I have created handmade felt Elizabethan collars to prevent feather plucking in lovebirds. I use thick 2mm felt, which is rarely seen on the market, so it won't bend or lose its shape. As someone who has struggled with feather plucking in my own lovebird and tried various solutions, I found that this shape and stiffness of collar made of felt was the most effective. Based on my experience, I am making these in the hope that they will be helpful to others facing the same problem. [Sizes] You can choose from two sizes to suit your needs: 8cm and 10cm in diameter. The sample is wearing the 8cm size. You can also choose with or without a hole. The hole is 2cm in diameter. My lovebird has a 2cm hole with 4-5 slits of about 2mm each. It's very sad to put it on your cute little bird... but sometimes they pluck their feathers to the point of bleeding, so I put it on until the wound heals. If you only want to use it in the cage and take it off during free-flight time, a snap closure might be a good option, but please check the images for the added thickness of the snap. ① 8cm diameter, no hole ② 8cm diameter, with hole ③ 10cm diameter, no hole ④ 10cm diameter, with hole ⑤ 8cm diameter, with hole, with snap +500 yen ⑥ 10cm diameter, with hole, with snap +500 yen If you want ⑤ or ⑥, you need a price adjustment, so please do not purchase immediately.
