Cosom Mini Golf - Set Includes 6 Putters, 18 Targets, 18 Foam Balls - 6 Assorted Colors

.... is mostly plastic. I say this because I bought a set unable to find real specifications, thinking that if they were not what I was looking for, I could easily return them. The set was not what I was looking for, plastic clubs (maybe 30" in length?) and a hard foam for the balls. All of this would have been ideal if I was throwing a party for 10 year olds inside. I was throwing a party for 4 year olds and wanted more of a pro mini golf feel. I was able to find pro mini golf clubs for about $12 each (with shipping) instead.So, I returned the set. This became a bit of a problem when one of the balls went missing. Even if I had lost the ball (within the realm of the possible) I was amazed to find out that they could not charge me for the one missing ball and refund the rest of the money.Apparently, there is NO WAY TO REPLACE A SINGLE PART OF THE SET. I am being told this is due to the set being checked and shipped from China, and the inability of Cosom by Cramer to order single pieces.So, if you were to have a club get damaged, etc, you would need to buy an entire new set.It appears we have reached a compromise, after several emails, of buying an entire replacement ball set, which will put me back $20 in addition to the already high shipping cost.All in all, if you are looking to drop $100 or so on a mini golf set, I would recommend a company like Western Golf (I'm not affiliated) and putting together a more rugged set yourself.
