Aquarian Studio Rings SRSET5

Comparing with old Remo,this Aquarian are much beter with a beter look and fit size precision.
I like the material,who does not make any extra noise,becouse they fit pit perfect in the drums. The option of 2 rings are great,becouse they are a bit thin then Remo and light,and the material they made,is type sticky. U will not see them flying away from drums easly. My old large ugly remos went all out,now only Aquarians. I can't find a Aquarium 13" ring anywhere,sadly. If someone know where I can find it,thank u.
