Slick has a very easy way to customize its buttons through two variables in its own configuration: prevArrow and nextArrow.

Both types are: string (html | jQuery selector) | object (DOM node | jQuery object), so in your settings slick slider you can set the classes:

prevArrow: $('.prev')
nextArrow: $('.next')

and add to these elements the styles you want.

For example:

//HTML
<div class="slider-box _clearfix">
    <div class="slick-slider">
        <div>
            <img src="img/home_carousel/home_carorusel_1.jpg">
        </div>
        <div>
            <img src="img/home_carousel/home_carorusel_2.jpg">
        </div>
        <div>
            <img src="img/home_carousel/home_carorusel_3.jpg">
        </div>
        <div>
            <img src="img/home_carousel/home_carorusel_4.jpg">
        </div>
    </div>
</div>

<div class="paginator-center text-color text-center">
    <h6>VER MAS LANZAMIENTOS</h6>
    <ul>
        <li class="prev"></li>
        <li class="next"></li>
    </ul>
</div>

//JS
$(document).ready(function () {
  $('.slick-slider').slick({
      centerMode: true,
      centerPadding: '60px',
      slidesToShow: 3,
      prevArrow: $('.prev'),
      nextArrow: $('.next'),
});

//CSS
.paginator{
  position: relative;
  float: right;
  margin-bottom: 20px;

  li{
    margin-top: 20px;
    position: relative;
    float: left;

    margin-right: 20px;

    &.prev{
      display: block;
      height: 20px;
      width: 20px;
      background: url('../img/back.png') no-repeat;
    }

    &.next{
      display: block;
      height: 20px;
      width: 20px;
      background: url('../img/next.png') no-repeat;
    }
  }
}
