How to increase the size of the variant box on Studio theme?

[RedesMI]

Hi, Shopify world 

I need help to edit the code of the variant box width, I need help finding the code or how to increase the size of the variant box. 

My variant models' names are getting cut, and I need them to be completely visible.

Here is an image of the issue (here the name is cut and the arrow is blocking the model name) 

 
Thank you in advance!
