If I used a spiral and insert replacement type, I switched to this because it was scattered by idling and stuck in the tire and getting out of the steering wheel. Price is also cheap. After that, it would be nice to have a repair plug 3 and about 10 mL of cement set for easy carrying.
Even if it pierces the hole causing the air leakage through the rubber plug and it pulls out, it will become about the insert tool as it is It will be too easy to break the hole through which the plug passes
It is useless because it is this price. Tip processing was sweet and bent, surface processing was not done and it was not possible to slip off and it required bending correction and polishing treatment.
