Amazon カスタマー 5 You get a lot in this thoughtfully put together kit. It takes some practice to know how best to scratch the line on a bottle and getting the alignment right ,so do not expect perfect results straight away - it is not the equipment's fault!I like the gloves which really are essential to use since there are micro glass chips created when scratching which will get under your skin. The supplied sandpaper is also good.There are a number of rubber bands of different sizes supplied to fit close to the scratch made to direct the boiling water onto the scratch line to optimise the heat stress (pour the water carefully into that channel).My only wish is that the drill bit for making holes was a much smaller diameter.
