The Pen Slim - Rilo 10.5oz Selvedge


Slim fit, medium rise, washed down black Japanese 10.5oz 4-Way Stretch Selvedge, zip fly, premium leather patch, and custom-branded hardware. Made in


Our premium denim is inspired by the classic vintage blue jean. Our Premium Japanese 4-Way Stretch Selvedge denim story starts in Japan where our fabric is developed at one of the oldest denim mills. We blend a unique 4 way stretch material with selvedge denim to create a specific amount of stretch and comfort you wouldn’t typically get with selvedge denim. This 360 degree of stretch gives the wearer comfort from every angle no matter what they are doing.

Our 4-Way Stretch selvedge fabric is weaved using vintage shuttle looms. Rolls of denim fabric are then brought into our workshop in Los Angeles where each pair goes through a 60 to 90 day process of cut, sew, washing and testing. With 4 fits available in multiple weights (see fit guide) and washes, the style options are endless.

Great Jeans, terrible customer service

So let me first begin by saying that I love these jeans. The fit, the quality, the look, are all on point, and I would LOVE to continue buying them, but the customer service experience I have had really gives me pause.

Here’s the story:

I recently ordered eight pairs (four different styles in two sizes each) to try on and see what fit and size worked best for me. After settling on two pairs that I really liked, I went to return the remaining six pairs of jeans only to find that there is a significant restocking fee (30%) for returns of six or more items. While I think that’s a pretty steep restocking fee ($400+ in my case!), I was the one who failed to read the return policy before purchasing so it was completely my fault. However, I sent an email using the customer service link on the site asking for mercy. 48+ hours go by, and still no response so I send another email and still, no response. Finally, after nearly a week of waiting to hear back from someone, I decided reach out to their Instagram account asking for help and thankfully, they promised to connect me to someone in the customer service department. After waiting another 24+ hours I finally get a response, with instructions for how to return the jeans and avoid the 30% restocking fee. I was grateful for their understanding, and so I box up the jeans and send them back. In my mind, the case is closed and I am looking forward to a full refund.

Fast forward a few days later. I receive an email from a customer service rep informing me that one of the pairs of jeans is no longer eligible for return as they have been altered! At this point I’m in shock. What?! Apparently, according to the customer service rep, they have been hemmed and are being sent back to me with no refund. So now I am being stuck with a pair of jeans that are too big for me. I replied instantly to the email informing the rep that I did not alter the jeans (I am 6’5” and so I don’t ever have a problem with jeans being too short, in fact, quite the opposite!) but that I also understand that there’s really no way for me to prove that I didn’t, so I asked if there was some way to resolve this?

Again, no response. Nothing. No reply to my questions, just silence.

The jeans arrived at my house today, and it does indeed appear that they had been slightly hemmed. I suspect that they had already been altered when I got them and that the Kato team had failed to pick up on it, leaving me to pay the bill. I can understand that my word isn’t worth much to them when they have the “evidence” but to just be completely ignored is, in my mind, bad form.

Again, love the jeans, but the customer service experience, at least for me, was not good.

Dear Whit,

We regret to inform you that our initial conclusion regarding the alteration of the returned item was reached without a thorough consideration of your perspective. Upon reflection, we acknowledge that we hastily returned the item to you without conducting a proper investigation. We intend to rectify this oversight and will be reaching out to you via email to address the issue in detail.

Furthermore, we wish to express our gratitude for your positive remarks concerning the quality of our product. Such feedback is invaluable to us and serves as a reminder of the standards we strive to maintain.

Best regards,

Rex Ivanovic

The Right Combination

The fit was perfect and the washed look made for a relished new addition. After wearing a couple of times, it fees like an heirloom that I've had for a long time. It's the perfect combination of fit and feel. Kudos Kato!
