Bisected section of a silicone brain "floating" in resin.
Clear on front, cloudy on back. The price changes depending on the slice. Ex: the slice used in the thumb nail photo is $60, it's the 1st slice of the 2 segments: B1 or B2. Buying in a set is also an option. Ex: full set B1,B2. By buying a set you save $5!
(This is before any coupons are applied)
(B1 is more expensive due to that segment being thicker.)
 
Measures 4"x 6" (?)
