As of January 9, 2026, our bicycle tube jewelry is ONLY available on Etsy or at live events. The link to our Etsy store is: https://www.etsy.com/shop/KadenandKai 

We receive donations from local area bike shops. The majority come from the Cycle Loft in Burlington, Massachusetts (now TREK). As people come in withe flat tires or service repairs, the shops set aside the tubes for us. We then pick them up, wash them, sort them, cut them and then wash them again!

Although all our products are made from used bicycle tubes, we have a multi-step process to ensure that all products are of the highest quality. Some of the steps we take are listed below.

1. We only use the parts of the tube that are not fully worn. Generally the sides of the tube are very high quality compared to the center of the bicycle tube.
2. We clean the tubes at multiple points in the creation process.
3. We use a standardized sizing system for all our jewelry so that all sizes are the same regardless of style.

There are a few ways you can make your Kaden & Kai Bicycle Tube Jewelry shiny.  One option is to mix one part lime juice with 3 parts olive oil. Once mixed, you can use a cloth, sponge or brush to spread the mixture evenly across the jewelry and then let it air dry. Another option is to use a rubber boot protector instead of the lime juice/olive oil mixture.

The shiny finish will make the jewelry appear to be darker black as well.

Note: This is not needed for Verdasil™ silicone jewelry.

No. We thoroughly clean all the tubes a few times during the making of the jewelry. Our jewelry should not leave any type of mark on your body. With that said, sometimes when taking the jewelry off the display card, you will see marks. This is generally from the rubber moisturizer we put on the tubes prior to packing them.

Whether you purchased the item for yourself or someone else, we are happy to exchange the item you received for the right size or provide an extender at no cost if we do not offer the size you are looking for. The steps to make the exchange are as follows:

1) Contact us by email at info@kadenandkai.com within 30 days of the purchase date and let us know what size you have and what you are looking for. If we have the size, we will exchange it for you, if we do not make the larger size, you will have the option to receive a free extender that can be cut to size, exchange your bracelet for another bracelet that comes in your size or receive a refund. We provide pre-paid envelops for exchanges.

2) To exchange the bracelet, get a refund or store credit, send the bracelet USPS first class mail in a standard envelop. The bracelet should be wrapped in a sheet of paper.

3) If you purchased the item and want a refund, we will refund you once we receive it. If you received it as a gift, we will provide store credit in the amount of the purchase.

4) If this is an exchange, once we receive the bracelet, we will send out a new bracelet in the requested size.

Since 202, all of our jewelry has been made in our Lexington, Massachusetts workshop.

Yes! Because polypropylene bags are woven using fabric fibers, they are typically made almost entirely of plastic, which means they are both fully recyclable and reusable.

The polypropylene bags we use are non-toxic, odorless acid free, and 100% food grade safe. Some suggestions for reuse might be to store snacks, make-up, kleenex or use as an on-the-go wallet when carrying a small purse or backpack since they can be resealed and are easy to see through.

We announce new products on Instagram, Facebook, on our website and via email in our quarterly updates.
