Home Row Bumps (Nibs) too big

The "home row bumps" look great. They are too big for a Nokia/BlackBerry phone though. I just measured the phone keys and we would need bumps that are 2.5mm in diameter or smaller. Can they be trimmed down?

Keytop Nibs (Bumps) to help identify keys

I have used your labels for big key stickers for my mom at home, and am now interested in whether or not you also carry nibs for a mobile phone to help identify keys for better keypad navigation.
