Pagination buttons not showing

I'm a bit perplexed with this. I've done pagination on 2 other sites of mine, without any issues (those were Laravel 5.1). This site is running Laravel 5.2.

Pagination is working properly, but not showing the buttons. I assumed the buttons were being rendered from bootstrap.css, but I couldn't locate it. Right now, the pagination links are text only (<< 1 2 3 4 >>)…no buttons.

Here's the DB query I'm running in my controller:

$numlist = DB::table('numbers')
                ->where('closed', 'f')
                ->orderBy('id')
                ->paginate(10);

And in my blade view:

{!! $numlist->appends(['oc' => '1'])->render() !!}`

Any ideas why my pagination buttons aren't showing up?
