Inflatable Air Wedge Alignment Tool

It's an inflatable air wedge for door and window installation. It's made of durable fiber-reinforced TPU rubber and features a quick release pump for one-handed operation. The dimensions are approximately 19cm by 11.5cm (7.48" by 4.52"). I only used it once after buying it because I accidentally locked my keys inside my car, so I pried the driver's side window open a little bit.
