Note: Each DnA Key is unique. Once each one sells, we won't have another one exactly like it, but we will eventually have more DnA Keys. These DnA Keys are made of an aerospace grade aluminum alloy, which is a soft metal, great for harmonics and sound healing. Because of this softness, they are very easy to scratch. They are all CNC milled for the physical construction and then manually polished for a mirror finish. To prevent and treat normal wear of the instruments to ensure a bright appearance, keep them wrapped in a soft cloth even while in their carrying cases. When hairline scratches and smudges from the mallets do occur and the finish begins to look dull, polishing them with an automotive metal polish is advised.

Earth Tuned DnA Key - Perfect 5th D / A (#RTT771)

Earth Tuned DnA Key

The Perfect Fifth is considered one of the most significant musical tones from a harmonic and metaphysical perspective. The Perfect 5th DnA Key is tuned with D = 288 Hz on one end and A = 432 Hz on the other, creating a perfect 5th Harmonic.

Not only do the notes D and A create a perfect 5th, if one examines the internal angles of a pentagram, you will find that they measure 36, 72, and 108 degrees – which are harmonic proportions of both D and A when utilizing 432 Hz based Pythagorean tuning methods. 72 becomes 144, which then becomes 288. 108 becomes 216, which in turn becomes 432.

These two geometric and musical harmonic proportions create a powerful combination which aligns with the harmonic design of human and natural bodies. It is one of the most powerful combinations for allowing us to slip into our subconscious mind and recalibrate our bodies with the harmonics of the universe.

Best flip-flops I've met
Size: 11, Color: Black/Geyser
Right away I was impressed by the thichness and cushioning of these flip-flops. They are not a flimsy piece of rubber under my foot. The sole is more like that of an athletic shoe with layers and an impressive tread. I've always found that my heel sits too much on the back edge of flip-flops, or even over it. So I ordered these just a half size large and they're perfect. The foot cradling allows my heel to sit down inside the flip-flop comfortably and securely. They're not about to fall off. The toe piece (I don't know what it's actually called) is not just the typical round rubber post. On these flip-flops it's nicely shaped and fits comfortably between my toes. The arch support is nice too. They're not just flat. In spite of being more substantial than the cheapies we all know, these remain lightweight. They clearly look better too

Well made
Size: 11, Color: Black/Geyser
The first thing that stands out about the Columbia PFG Castback Flip sandals is the solid build and clean fishing-inspired design. The Black/Geyser color combination looks sharp and matches the product photos well. The straps feel durable and comfortable against the foot, and the footbed has a slightly cushioned feel that makes them comfortable right out of the box. Overall construction feels sturdy, which is what you’d expect from something designed for outdoor or water use. In everyday wear, the sandals are comfortable and easy to walk in. The footbed provides decent grip and support, and the textured surface helps keep your foot from sliding around when they get wet. They work well for casual use, whether it’s around the house, at the beach, or after a day on the water. The lightweight feel also makes them easy to pack for trips or outdoor activities. After wearing them for a while, they hold up well and remain comfortable for daily use. The materials seem durable and the straps stay secure without stretching out. They’re simple, reliable sandals that work well for warm weather, boating, or casual summer wear. Overall, they’re a solid choice for anyone looking for comfortable flip flops with a slightly more rugged outdoor style.

Extremely comfortable with slight roomy fit
Size: 11, Color: Black/Geyser, Size: 11, Color: Black/Geyser
These are easily the most comfortable flip flops I have ever owned. From the moment I put them on, there was no break in period at all. They felt soft, supportive, and ready for all day wear right out of the box. The cushioning is excellent without feeling too soft, and they have a nice stable feel when walking. They are lightweight and clearly made with quality materials, making them great for everyday use or around water. One thing to note is that they run a little on the larger side, so if you are between sizes, you may want to consider sizing down for a better fit. Overall, these are a great combination of comfort, durability, and function. I would absolutely recommend them, especially if comfort is your top priority. (Excuse the teeth marks- my dog unfortunately got ahold of them before I snapped the photo- they are PERFECT out of the box)

Comfortable Flip-Flops with a Clean, Sporty Look
Size: 13, Color: Black/Geyser
I picked up the Columbia Men’s PFG Castback Flip in the black and white colorway, and the first thing I noticed was how comfortable they felt right out of the box. How They’ve Been Used: Even though it’s still winter, I’ve been wearing them around the house occasionally to get a feel for the fit and comfort. I plan to use them more regularly outdoors once the weather warms up. What Worked Well: Immediate Comfort: The footbed feels cushioned and supportive without needing a break-in period. Secure Fit: The straps sit comfortably without rubbing or feeling stiff. Lightweight Design: Easy to slip on and off for quick wear. Clean Style: The black and white combination gives them a sharp, versatile look. Positive Feedback: My wife has already commented on how good they look. Things to Keep in Mind: Seasonal Use: Best suited for warmer weather and casual settings. Sizing: Checking the size guide helps ensure the right fit. Bottom Line: Based on my experience so far, these flip-flops offer a great balance of comfort and style. They’re comfortable enough for everyday wear and look sharp enough for casual outings. I’m looking forward to putting them to full use once spring arrives.

Columbia always makes great stuff
Size: 14, Color: Espresso II/Black
Even with my flat feet these offer a lot of padding which makes these extremely comfortable. They increase my height about an inch haha. These are great for walking around the beach or just going for walks. The tread on the bottom of these make walking up hills where the surfaces are not completely even extremely easy and very grippy. Time will tell how durable these are, but so far they're holding up very well.
