Bats are a natural product and there is a chance they can be damaged due to a bad contact with the ball without any fault in bat design. Therefore no guarantee / warranty is possible. However, we do have a return policy – You can order our bat and return it for a full refund within one week of receiving it as long as you’ve not played with it. So, you can get a feel of the willow quality, bat balance and our handle design and if you’re not satisfied we’ll take it back.
