Bọt biển đánh bóng

The coarse side took care of deep scratches in no time, and switching to the finer mesh gave my spinner that smooth, factory-like finish. I went through all four sides and each one clearly did its job. For the price, this sponge is a steal.

The different mesh sides make it so easy to switch between rough sanding and a fine finish on my fidget spinner parts. I grabbed the multi-sided version and honestly, it's already become my go-to for quick touch-ups.
