Introduction

Backbone Adapter is a product you compare on the printed spec. Size, count, or model. A thumbnail is not the spec.

  • Compare size, material, and what is in the box.
  • A thumbnail is not the spec. Read the card.
  • Keep the first order small if the brand is new to you.

Keep the first order small if the brand is new to you.

FAQs

Match the spec on the card: size, model, or count. A lifestyle photo is not the spec.

Only if you will use it this month. Jumbo packs go stale or unused.

Follow the listed care. Heat, bleach, or soaking can ruin a first-order sample.

Only if the card says a battery, glue, or a tool is sold separately.

Daylight, not a phone screen. Order one first if the shade is numbered differently by seller.
