Hi Fam, it's been a while we launch the last mini Viper (around 2 months I believe). We would like to do something new to this design. So M390 was selected this time.
Material: M390 steel (heat-treated)
2 SS balls
* GIFTS for YEC's member is a pair of Glow balls, we just have 10 pairs, so if you purchase early, you might get them. You will know when you receive your M390 Mini Viper spinner
Note: This sales started on 10 March 2020. Currently, we couldn't ship to the EU as nCOV19. If you intend to purchase this item, we can not ship these days, but we will ship quite late. Sorry about that, thank you so much.
