Surprise! We are currently selling Trial and Error cups! The smaller and silver cup on the left is for $15.00 and the other bigger one on the right is for $20.00. They are available online, any events that we are attending in the future, and any fine local retailers! We hope you would enjoy these lovely cups of ours to hold your drinks at a robotics event, on your way to work or school, or maybe even when you are on a run!
