Press-Buckle Design: It is super easy for adults to maneuver and d to use, but complicated enough where kids and pets can't go through everything. Ultrasonic Bonding Techniques: All parts of the item are fused together by ultrasonic welding. No matter how down it is, the two small pieces from the top of the item will never fall off. Don't worry about your kids putting the little button plug in their mouth. Strong Adhesive: The adhesives are very strong as 3M tape just isn't strong enough for us so we researched and found an even stronger adhesive to keep our toddler from hurting. (You can deduct this by heat (hair dryer) for a minute or two and it comes out easily.)
