Text size

Hello,

I’m using your extension, thanks a lot it’s very useful. I just have a problem with the button because the customisation of my products is long like this word : lisse, rainuré, lisse chrome and rainuré chrome.

Is it possible to use more than 3 letters without display problem?
Is it possible to adjust the font size of text?

I would like not to increase the size of the button and I can not find other solutions.

thank you in advance
