Here are my new favorite icon packs!

I think they look stunning with Bubble Cloud Widgets. Both are from Vertumus and both are paid, I found them because they are on SALE!

I think it looks best if you set the bubble colors to 50% transparent. Similar trick as used with the Neon pack before.

DIVES
This pack has over 3600 icons! It’s best to set the bubble color to full transparent with this one, unless you’d like a contour around them.
