Stroke Maker Paddle 0.5 Orange

These are stroke maker paddles that were used at a swimming club.
I upgraded from the purple ones I had used for many years, and after using these for a year, I switched to a different sport and stopped using them. Over time, they tend to bend slightly due to water pressure or hand strength, but these are not yet warped.
There are many small scratches from friction.

How about using these as a spare in case you lose yours?
