I bought this from a seller last week. I decided to not switch over to 5mm bullets. Previous seller sells very well taken care of parts. from previous add "Only used for 15 minutes in my SCT410. Pack was purchased brand new from A Main Hobbies a few months back."
No puffing that I can see. Pack sits flat on the table.
New Protek 5mm bullets and balancing plug are included. 70 shipped.
