Brilliant quality
I have been wearing this t-shirt almost every week for years and it still hasn't faded - highly recommended for the quality as well as the great design.

Great t-shirt for any geeks out there. My son loves this and is annoyingly reciting Pi to around 100 digits. Good fit to his age.

Brilliant
Great t-shirt and great fit. It had a smell of vinegar so I had to wash it before wear. That is due to the printing process and doesn't affect the quality of the t-shirt.

Ok for price
Bought for science mad 12yr old son. I was worried that it would be too small as it’s 11-12yrs but longer in length than I thought. Quality is ok but not washed yet, happy with the price I paid
