They turned out exactly as we had hoped and we looked good even when we didn't bowl well. The printing was perfect and you can only see 9 pins on the shirt(the 5 pin hidden behind the headpin) which worked for us as we bowled in a 9 pin No-Tap league.

The shirt I ordered was too small. I contacted Zazzle and they replaced it with a larger size. Very happy.

Great t-shirt!!! Quality is amazing and the colours are vibrant. Exactly how described!!! Can’t wait for my daughter to ask and give it to her confirmation sponsor. It’s also came earlier than I expected. Colours were exactly what I expected. The quality is amazing. The images couldn’t be any better. I’m very happy with his product and highly recommend it.
