Open it but keep the box and just be careful with it, as you should be with all of your toys as a collector or modelmaker. That's my take at least. I've, for better or for worse, opened every single one of my Plarail and Trackmaster products I've acquired over the years. I never had a good opportunity to use nor the allowance to afford huge lots from stuff like Jauce or Buyee, so everything I bought was usually from Ebay or brand new on Amazon. Back then new in box stuff also wasnt worth upwards of 100 dollars (except for Oliver, but I also ended up opening him, not realizing he was a dime-a-dozen over in Japan and the UK. I'm still not regretful about him tho since now a boxed Oliver would be worth at least 200 if Ebay is anything to go off of)
