I have a used Butterfly Spinart 1.9mm, BLACK. It is cut for a wider blade. It is in good condition but with glue build up. I have used this for a month.
Butterfly introduces the newest Spring Sponge rubber, Spin Art. Spin Art
is the spinniest and most-balanced offensive rubber in the Butterfly
line. Spring Sponge technology combined with a hard sponge and a sticky
top sheet make this a very dynamic rubber. Spin Art provides great
speed, with more spin and control than Butterfly’s bestselling Spring
Sponge rubber, Tenergy. So feel free to dig into those pushes and load
up the serves.
