Replacement straps (bands) for 20mm smartwatches, etc. Color: Black. Material: Silicone. The adjustable buckle uses a magnet for stepless adjustment, making it easy to put on and take off, and providing a good fit. Images 1-4 are promotional images from the manufacturer. Image 5 shows the item for sale. If it's 20mm compatible, you can easily replace it with a hook (see image 4). I also have various 22mm straps (bands) for sale, so please take a look if you'd like. Note: This is a personal sale, not a shop, so there is only one of each item. Made in a foreign country. Please purchase only if you understand this. If you are overly concerned, please refrain from purchasing to avoid any trouble. Items will be shipped within 1-2 days, but there may be a slight delay depending on the timing. If you have any questions, please use the comment section. I will answer as best I can. I am also selling on other platforms, so I may remove the listing depending on the timing. Thank you.
