This is a large reusable kabob filled with those irresistible birdie bagels. The kabob itself is 19" long, and is to be used on cages with bar spacing of 1 1/2" inches or less. It's solid stainless steel, so you know it's safe, and will last for many years to come. It has one X-Large 9" bagel tube, one macaw bagel, one large 6" bagel tube, three 4" and three 3" bagel rings, two bagel tubes, and three mini bagels. If you purchase these items individually, they would cost you over $45.00. Buy this toy, or the refill kit, and save money.
