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.

Rectangle shape covers & adheres well.

Size: 24 x 35mm

This is a rectangle shaped patch that I prefer over circular patches. Covers well and gives new life to inner tubes on the used bicycles I repair to give to charities.
