What's not in Sulit?
and what won't factories in China make?
aamd of Sulit is selling the adapter for Php 220 and the cutter with 2 free adapters for Php 1,700.
Alternatively, if you're not too fussy about rough edges, you may use a pair of scissors to cut your regular sized sim for free. Globe has released PR on Tattoo MicroSIM - powered by a new Php 999 Unlimited Data Plan - but I'm not sure if it's available as yet.
