I have two young boys that love to collect things. I was talking to them about sports cards and think I would like to get them a few packs/boxes to see if they like them. I collected cards as a kid but haven't been in the hobby for 30 years or so. 

Does anyone have recommendations of good products that would be relatively cheap to get kids started? I was hoping there may be Ohio State Football specific sets but all I see is the ON-IT cards and I am not familiar with the company or product. What should I get these kids to give them a taste of sports card collecting? They are not yet into specific teams or players so much as I think they would like cool looking cards, etc. 

Any thoughts or advice is appreciated! Go Bucks!
