Challenge
Before

For antiques and curios buyback, “bringing items to a store,” “submitting ID and bank details on paper,” and “anxiety over not seeing the appraisal price” became psychological and physical hurdles for users, causing missed opportunities to list items.

  • Sell heavy, fragile antiques from home without bringing them to a store
    Heavy burden of drop-off and packing
  • Decide whether to ship only after agreeing on the appraisal price
    Anxiety over not seeing the appraisal price in advance
  • Complete ID verification and account registration securely, with no paper mailing
    Several days of lead time due to paper mailing
  • Track appraisal, shipping, and deposit progress in real time
    Opaque progress generating inquiries
