Are you guys double sleeving $60 pre-cons?

I’m brand-new to magic the gathering, been playing for about a month now. I have the Explorers of the Deep precon.

I read that in order to best protect your cards, you should be double-sleeving them. Thus, I bought some dragon-shield perfect fit inners and matte standard sleeves, and got to work.

I found out the hard way 100 double-sleeved cards simply aren’t going to fit in the mage-tech commander lite box. In hindsight, the description on their site is pretty clear about that. My bad.

Should I buy a larger deck-box to accommodate, or am I going overboard here?
