How much will this Stop Overreacting Funny Nerd Jokes Chemistry Test Tube Flask shirt shrink?
The 100% cotton fabric is pre-shrunk during manufacturing to minimize shrinkage. However, like most cotton garments, slight shrinkage (typically 3-5%) can occur, especially if washed or dried with heat. Following the cold wash/low heat dry instructions helps maintain size.
