Arrived on Time
Size: 24 x 35mm
My package arrived on time. They are thick, and seem to be made of quality materials. I have not needed to use them yet, but will I update my review when I do.

Not what ad picture promotes - just patches - no more
Size: 24 x 35mm
For twice amount of money that other tire kit repair offer - it has no glue, no lighter fluid, no scratch tool - just top $ for patches. Show in video how to fix, but after you get it you'll find that you need to go back online and order, glue, lighter fluid, scratch pad, and perhaps even a roller tool. Just order a kit with needed accessories & patches to start with at half the price.
