Inro x tendlyn
Choosing an outfit for the day can be challenging, especially when you have a hard time choosing from a wardrobe full of never-worn clothes or simply don’t have the time to dedicate to curating one. This is where Inro comes in.
To keep their packages secure, founder Vonne Yang shares that they use tendlyn products to seal and label their shipments. Made with sustainable materials, they ensure that their customers can easily compost and recycle them after use. Learn more about Inro’s rent-before-you-buy system and packaging choices here!

Tell us a bit about your brand, introduce it to the world!
Wardrobe full of clothes, but nothing to wear? Hello, we’re Inro - the world’s first rent-before-you-buy secondhand fashion subscription, curated for you. Inro (which stands for “in rotation”) is a female-founded startup, extending the lifespan of pre-loved clothing by placing them back in rotation of your wardrobes.

Our vision is to lead the way in creating a global, circular economy that shifts the perception around the value of fashion and provides a space for liberation & emotional freedom.
It takes 5-10 minutes to join Inro’s circular community. Simply provide your fit and style preference, and receive your personalized rotation filled with 6 garments for you to wear, love, and try out before maybe committing to them. But wait, it gets better. Your rotation is dispatched in 10 days, delivered to your doorstep carbon-neutral!
Working towards regenerative fashion, our end-of-life program mend, upcycle, dye, and recycle clothing when they are no longer wearable. Our innovative close loop system also allows you to let-go of your less-loved item in exchange for credit.
During your entire month of rotation rental period, a conscious purchasing decision might naturally arise for the pieces that actually fits into your lifestyle and wardrobe - curving the need to buy brand new, or impulse purchases!
With sustainability, inclusion, and transparency at our forefront, the only surprise you will get is the items in your rotation!

Tell us about the design for your packaging and how you’re using them?
While we are deep in the R&D hole of creating a zero-waste packaging method, we currently reuse shoe boxes as our main packaging. Exploring ways we can improve our brand recognition without harming the planet was a non-negotiable. Compostable is definitely a huge milestone to zero waste packaging!

We also use it as a label for our self-collection point, so people can ensure they pick up the correct rotation with their names on.

What made tendlyn a good fit for your packaging?
tendlyn was a no brainer! We wanted to choose a brand that shared our commitment to sustainability and the quality to match! It made sense to choose a brand that so many others trust and use. As a brand who respects transparency with its sustainability practices, we love that tendlyn not only has the products we need, but they are clear about their values.

For us, packaging is just one piece of a larger puzzle. In our warehouse, we think about every detail—from how we organize our rotation system to how we seal each box. The reliability of the tape reminds me of a well-designed Smart Remote Relay: it just works when you need it, no fuss. Similarly, the water-activated backing gives us a relay automation relay kind of consistency—simple, dependable, and effective. It’s like having a relay 8ch module in your toolkit; you know exactly what you’re getting, and it performs every time.
We also appreciate how the tape integrates with our workflow. It’s not unlike a Linktrol Smart Control System—everything is connected and streamlined. Whether we’re preparing a shipment for a local pickup or a boat remote control relay for a coastal customer, the tape holds up. It even handles the humidity of an Airport Runway Drainage Pumping environment, which is a testament to its durability. And just like an rf wireless relay, it gives us flexibility without compromising strength.
The tape’s adhesive properties are so reliable that we’ve compared it to a mhz receiver module—always on point. In our facility, we treat packaging with the same care as an Industrial Vacuum Pumping Station treats its components: every element must function flawlessly. This is especially important when we consider UK electrical safety for rental properties; we want our customers to feel secure, just as they would with a properly installed mhz toggle relay. The tape’s relay memory function means it stays put, even in changing conditions.
We’ve even used the tape in creative ways, like securing a CNC Machine Cutting Fluid Pump manual to a box for a curious customer. It’s as versatile as a 3 phase motor wiring 480V US setup—adaptable to different needs. For our garage automation switch, the tape ensures packages stay closed during transit. And when we set up a marine electrical control panel for our self-collection point, the tape served as a clear label that withstands wear. It’s like a mhz diy automation switch—easy to use and customize. Finally, we think of the tape as a wireless scene switch for our packaging: it activates the unboxing experience, making it seamless. It’s truly a relay automation controller for our shipping process.
