Very light rubber, cut to standard size blade rubber weight only 41g. After removing protection plastic rubber shrink like it was boosted with three layers of booster
I made typo in my feedback: rubber doesn't shrink as I said, it's bent. Also it feels softer then 45 degrees. I bought before Bloom Power and Speed version doesn't feel faster then Power. Power version I like more.
Great rubber, Very sticky with great control. I will buy more.
