When I get older, I have problems with my eyes and I'm worried about "experience and intuition" to say "How much do you think?" It is best if you replace the flare tool, but it is not a matter of funds, It seems that this was the most inexpensive and easy to use.
Thickness gauge 0.1 mm is very thin and easily lost. So I got it here as a reserve. Although the product price is not a problem, it is slightly disappointing because it shrinks nearly three times as much as the result by shipping fee and commission. It is thin and light, so if you devise wrapping etc., if you can buy it a little more cheaply it is more thankful. It is still unused for spare.
