Can you just put 99 for values over 100?

I have tabs that navigate to different list, and a badge button on each tab that displays how many values are in each list. It's difficult to fit 3 numbers into the small badge button. If I extend the badge button too much, it looks odd for the numbers 1-9. When I put 99+, you can barely read it.

My question is, is it OK to put 99 for values that are over 100? We have a max of 100 anyway, so I was wondering if users understand that 99 means it's filled or if I need the plus at the end.

Thanks
