Generally, the front part of a tape may be seriously worn-out after
a period of using, while its later part is always brand new, which
results in a great waste. The direction for use of this tape is
basically the same with general one. Its greatest characteristic is
that it can be broken off at any place of a meter and each place has
a mark and two round holes. The tape head can just buckle in these
two round holes to form a new tape. And the head of tape can be used
repeatedly as well.
