Sturdy, high-quality components
Color: Vivid Orange1, Size: 16pcs
Well-made reamer and plug inserter, as well as the 10 plugs, and the accessories. Even the pouch is high quality. Included instructions are very clear -- just be sure not to insert the plug with too much force, or you'll put the entire plug thru the hole. It's so much easier for a simple in-situ scooter tire puncture repair, where removing the tire can be much more time-consuming than removing a car tire. Including the high-quality little water/soap solution mister is a thoughtful feature. I highly recommend.

The small set is convenient to carry.
Color: Vivid Orange1, Size: 16pcs
It works well and has a non-slip handle. Although there aren't many blades, it's enough for a family. The accessories are small but practical.
