w3n, normally the removal is FOC if u do another new set. if not, then like what mich mentioned, it's about $20-$30.
for soft gel, sometimes i remove myself cos it's quite easy, jus soak ur nails in the gel remover solution and wrap it using aluminium foil for like 15 mins, everything will be peeled off automatically. hehe.
btw, i did my soft gel at FEP, Iputa. quite a popular nail bar if u search online..price is reasonable too. my gel nails can last about 1 month each time.
i'm planning to send the invites to my friends in mid april, will try to distribute to them personally cos mostly are close friends and we do meet up frequently, else, will do it by post. for colleagues, i will just give it to them in late apr..
