This cement uses limonene extracted from citrus fruits and is very safe to use and comes with no unpleasant smells. It can be used for plastic model assembly as well as for cementing plastic plates and beams. Also, this cement has a strong initial adhesiveness not seen with other limonene cement items. The bottle's cap comes with a convenient brush. Extra thin cement is very useful for plastic model assembly as it can be flowed into areas like small gaps between plastic parts and does not leave marks when dried. 1 bottle contains 40ml of cement.
