In winter, thicker clothes made the seat belt feel like it was pressing against my stomach. I was curious whether that tight feeling would change, so I tried the provided Migijae seat belt extender clips. ## What were the price and package contents like? At the time the original post was written, the price was ₩13,900 for two. It said buying four would be a little cheaper, although no exact price was listed. The design was glossy black with no car-brand marking. ![Product information for black seat belt extender clips](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-01-e3cdb-900.webp) ![Information about the seat belt extender clip set](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-02-8amq6-900.webp) It is designed for one-touch installation, so the connection process looked simple. ![Seat belt extender clip examined before installation](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-03-112lt-900.webp) The box contained two clips. I liked that there was no excessive packaging. ![Simple box packaging for seat belt extender clips](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-04-t3max-900.webp) The product description introduced a high-gloss finish, alloy material, and reinforced alloy pin as features. What caught my eye was its simple shape and shiny finish. ![Exterior and finish of a seat belt extender clip](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-05-n8s15-900.webp) When I opened the box, the two were placed side by side. The simple setup suited my taste. ![Two seat belt extender clips inside the box](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-06-122q6-900.webp) After taking one out, I could see the glossy surface, and its lower part looked similar to the end of a regular seat belt. ![Glossy seat belt extender clip removed from the box](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-07-1keh3-900.webp) ## What was it like to connect and remove it in the car? There was a round button on top of the clip. Like the red button on a regular seat belt buckle, it releases the connection. ![Round button on top of a seat belt extender clip](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-08-jqdcb-900.webp) In the car I tried it in, it fit well even when I turned the clip front to back. ![Seat belt extender clip fitted into a car buckle](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-09-xvnao-900.webp) ![Connection between the car buckle and extender clip](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-10-115qm-900.webp) Once the clip was attached, it seemed to open the angle slightly and create some space. It clicked into place when connected, and I pressed the car's regular red button to remove it from the vehicle buckle. ![Removing a seat belt extender clip from a car buckle](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-11-1c84r-654.webp) Connecting the seat belt to the clip was simple too. ![Regular seat belt connected to an extender clip](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-12-qbc34-900.webp) After connecting it, I put on my long puffer coat and wore the seat belt. ![Comparing seat belt comfort while wearing a long puffer coat](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-13-1ogt0-900.webp) ![Comparison of a seat belt and extender clip worn over a long puffer coat](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-14-1b0oy-900.webp) ## Did it change the pressure around my stomach? Because I was wearing a long puffer coat, the before-and-after difference did not show clearly in the photos. Still, it felt more comfortable to me because my stomach felt less constricted. ![Seat belt connection while wearing a long puffer coat](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-15-lmfly-900.webp) At first, I wondered whether the extra length of the clip alone would make a difference. Once I wore it, the straight section of the clip made my stomach feel less pressed. When I pulled on it by hand, it did not come out unless I pressed the release button. ![Seat belt extender clip connection pulled by hand](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-16-xg6sq-900.webp) ## Did I check the back seat and child-seat use too? I also looked at the rear-seat buckle area. I came across information saying belt extension may be needed when installing a child seat, but I did not install a child seat myself and did not have sample photos. ![Rear-seat buckle area checked for extender clip use](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-17-aiuyb-900.webp) The original post introduced this as a product compatible with front and rear seats and all vehicle types. However, I did not personally check it in every type of car. ![Product information about seat belt extender clip compatibility](https://img.superchart.com/images/errify-seatbelt-extension-winter-use/errify-seatbelt-extension-winter-use-18-1mt9w-900.webp) The original post also mentioned that the clips can be connected to each other. The change I personally noticed this time was less pressure around my stomach while wearing a long puffer coat. ## Products - ErrifY car seat belt extender clips, 2-pack — Migijae - ₩13,900 (2개, 2026년 1월 30일 작성자 기준) (Jan 30, 2026) --- Superchart · https://superchart.com/en/@while-kettle-warms/errify-seatbelt-extension-winter-use/ · https://superchart.com/llms.txt
