    Team Unboxify

    Icon for groupLearn more about us.

    Oh, Hello there! We're unboxify, It's really nice to have you here.

    We're a team of e-commerce and gadget experts driven by four basic ideologies -

    • Deliver the best value possible to our users 💰

    Our moto is to maximize the value that we can deliver to our customers, when you buy with us you can be super-sure that you are getting every worth of your penny and we work super-hard in the background to ensure this while maintaining top-notch product quality. That's why all our unboxed products come with a minimum 30% off on prevailing retail prices which run up to 60% (which is even less than factory prices 😉). So, why buy one new when you can have two unboxed at the same price?

    • Never compromise on product quality ⭐

    All our products are passed through a stringent 8-step quality check process before making their way to your doorstep. It's super hard for a defective product to not get caught by the laser-sharp eyes of our quality check team. That's why we boast of an industry-leading <2% defect rate (which is even less than a brand-new product's average defect rate). So, you can be super sure that you are only getting the best quality mint condition products the next time you shop with us.

    • Only stock the best products out there 👌

    You would have noticed that we only have a very limited catalogue of products, the reason being that we only stock the best SKUs out there; which are carefully selected and curated by our product team based on multiple product quality & brand after-sales support parameters.

    • Do good for the environment 🌱

    While you are taking care of your pocket, you are taking care of the environment as well. An unboxed device represents 80 kgs off of our collective carbon footprint.  Manufacturing a new device produces about 86 kgs of CO2e. Unboxed Products? Just 6 kgs. Lose the weight: no extra effort, just extra savings.

      Now a bit about our background, we will try to keep it less boring huh,

      Unboxify is the brainchild of Tanishq Agarwal (IIT-BHU Alumni), our e-commerce journey dates back to 2017 when we started off as marketplace sellers on Amazon & Flipkart, where we are Top-Rated (4+) Sellers today. Our unboxed division was started in 2021, with the vision of resolving the ever-increasing amount of global e-commerce returns (which has touched a GMV of $800 Bn in US alone - 2021 Data).

      These unboxed devices although rarely used and in mint like-new condition, often found it difficult to be marketed through proper channels due to the lack of dedicated websites and awareness among customers (most people confuse unboxed products with refurbished or used 😔, which is not the case at all). Thus, these products often ended up landing in grey markets or being sold off as new units due to their spotless condition. So, to deliver these spotless products at the best value possible to users & to keep these unboxed devices from going to bad markets or ending up in landfills we came up with Unboxify.

      We at Unboxify strive to provide you with the best ever shopping experience humanly possible. Lastly, we would just say try us out once and we are pretty sure the next time you would need another gadget you wouldn't have to look at multiple places, you would know where you have to come 😉. See you on other side....Ciao!!

       

      Unboxify - Good for pocket, Good for Environment and Good for Society too 🫶!!

      Good to Know - 5% of our net proceeds go to human causes such as Mid-day Meals, Relief Works, Hospital/School operations for the needy etc. We have patronage with multiple NGO's such as Akshaya Patra, Narayana Seva Sansthan & ISKCON India. So, take pride 🌈 in your contribution to society while taking care of your pocket & environment.

      The Spirit of Phoenix 

      Our Registered Trade Licence is under the name of Phoenix Retail Inc & that like other things has a backstory to it. To those of you who are un-initiated Phoenix is an immortal mystical bird described in Greek Mythology (think of it as the Greek counterpart to the Indian Mythological Bird Garuda) that cyclically regenerates or is otherwise born again. Associated with the sun, a phoenix obtains new life by rising from the ashes of its predecessor. Only one phoenix exists at a time, and so when the bird felt its death was near, every 500 to 1,461 years, it would build a nest of aromatic wood and set it on fire. It is said to die in a show of flames and combustion 🔥.

      All the Harry Potter fans would be able to relate here (a high-five 🙌 to all of you out there),

      The phoenix bird symbolizes hope, progress, eternity, immortality and resurrection. In fact, Phoenix is a general symbol of happiness and good fortune. 

      In a small but similar way, we at Unboxify carry the same resurrection spirit of Phoenix with us. Every time we list a product on our website we are resurrecting it back again in the market and just like a Phoenix comes back young & better from the ashes of its predecessor. Our product also comes off better than what it was - when it was new, considering the overall value the product is now delivering to the customer while fulfilling all of its use cases & objective. Kudos 🙌.

      ~ Remember, Phoenix Always Rises from Ashes 

      Screw New. Become part of the last big thing in Tech.
