This easy-to-use repair kit consists of a rasp (a tool for roughening the edges of the puncture hole), an insertion needle tool for inserting the tyre seal, 3 strips of tyre seal and an instruction manual in English and Finnish. It's a very inexpensive way to fix small punctures in tubeless tyres. Keep in mind, however, that road traffic rules and regulations primarily recommend that a punctured tyre is replaced with a new one.

If you don't have the proper tyre repair tools, you should also purchase the repair kit.
