But the average girl doesnt have a strip of fibreglass to hand
So why not use......
A tea bag,yes ladies a tea bag
simply cut off a small corner of your tea bag,large enough to cover the broken area
paint your nail with clear varnish,stick the tea bag piece over the broken area,then simply apply another coat of clear varnish to seal it,and let it dry
Your nail will now be temporarily mended,woopi
