Let customers speak for us
from 2033 reviewsVery well made, just like the picture! I love my Benito laser engraved owala. I got the 40oz, bought a silicone boot from amaxon for it to protect from falls and bumps.
My daughter in law is a huge Star Wars fan and loved this gift. The engraving was perfect and it arrived timely. Very impressed by the service after being duped by other online purchase I’ve made lately.
I love my cup!!
Beautiful shirt! Love the quality!

magnificent
Amazing! So happy how it turned out, just as described!
Very fast indeed! So glad I purchased it!
Perfect! Came as described, very fast as well!
This cup is stunning, I couldn’t love it more! Shipping was so fast as well. Highly recommend this product!!!
I get compliments on this daisies tumbler all the time!! It was so well done.
I Love It! I have tumbler decor but it only fits Stanley Tumblers. Since some of the decor was more Halloween like I knew I’d have to get a Halloween Stanley tumbler. I finally found this one and fell in love with it instantly! With the tumbler having Halloween icons and quotes makes it even better! A little pricey but otherwise worth it!
About Us
Hi there! We’re Jose and Justin, the duo behind Mountainside Customs (formerly J&J Laser Engraving). Our journey into the world of laser engraving started in a way we never expected—by buying a couple of full-wrap engraved Stanley tumblers on Etsy. At around $160 each, we couldn’t believe the price. A family member was experimenting with laser engraving, which got us thinking: for just a few hundred dollars, we could invest in our own laser, create our own designs, and only pay for the cost of the tumbler itself. And just like that, the idea was born.
We started small with a single diode laser, making custom designs for friends and family. Their encouragement told us we were onto something special, but we quickly realized that a diode laser just wasn’t powerful enough to keep up with our ideas. So, we took the leap and purchased our first CO2 laser engraver. With that, we officially launched our Etsy shop in the fall of 2023. It took a few weeks to land our first order, but when it happened, we were over the moon.
One of our first major hits was our Disney Characters design—something completely unique on Etsy at the time. Customers went wild for it, and before we knew it, it was featured on Chip & Co as a must-have piece of Disney merchandise. Demand skyrocketed, and we found ourselves scrambling to keep up. We had to start limiting our available stock daily and quickly invested in a second laser to keep up with orders. Things just kept growing from there!
In mid-2024, we made the decision to move away from Etsy and launch our own site, JandJLaserEngraving.com. This shift allowed us to have more control over our business while keeping prices as low as possible. We believe that paying $160 for a full-wrap engraved tumbler is absurd, and we are committed to offering high-quality designs at a fair price.
Today, we continue to operate out of our basement, which we’ve transformed into a dedicated engraving workspace. We now run three CO2 lasers—Wanda, Timmy, and Cosmo (yes, named after The Fairly OddParents). During peak times, we also have two additional CO2 lasers at family members’ homes to help with order fulfillment. As of early 2025, we’ve sold approximately 7,000 tumblers across 6,000 orders!
Our passion for creativity doesn’t stop at engraving! We've recently expanded into 3D-printed accessories like Stanley toppers and straw sleeves, thanks to our newest addition—our 3D printer, Jorgen Von Strangle. And we’re not stopping there—very soon, we’ll be introducing even more new product types to our lineup.
We’re incredibly grateful for the amazing support from our customers, and we can’t wait to keep bringing you high-quality, custom-engraved tumblers and more. Stay tuned—there’s a lot more to come!
