Rollerblade

About 15 years or more passed since I bought Rollerblade "Aero blade" (?)  and "Cool blade". 5 years ago, it works well without fault.

These days, when I wore them to play it, the shell was cracked and broken...

Plastic has characteristics of fragile (brittle) due to oxidation degradation and fatigue.

Total cost was about 100 k JPY, so that I feel sad although long time has passed...

I should check how much is that.
