It's $20 http://www.sephora.com/browse/product.jhtml?id=P123900&cm_mmc=us_search-_-GoogleBase-_-datafeed-_-allpdts&_requestid=42976&ci_src=17588969&ci_sku=877969
If I don't lose it, It'll last a couple of years I expect?

usually most of them are at beauty supply stores, buty a there pretty good quality

How long will the tweezerman slant last?
