Lightly Waxed Canvas
The premium canvas* we use is coated with a light layer of proprietary wax, making the outer shell highly water-resistant. Unlike fully-waxed canvas, it won’t have a wrinkled or cracked appearance over time and with continued use.

The canvas feels dry to the touch (fully-waxed canvas typically feels waxy or damp) and it will not transfer onto other materials like your keyboard case, clothing or other items it comes into contact with.

* This is a special textile produced by a family-run business in the USA since the 1830’s. They are one of the last companies still producing this kind of high quality material.

Cotton Twill Lining
A tan coloured, 100% cotton twill lining makes for a soft and sturdy interior with no loose fibres. No more worrying about snagging your keycaps or static electricity buildup.

Leather Pull Tab
Made out of a beautiful, vegetable tanned English bridle leather the pull tab makes it easy to secure your keyboard with minimum effort.

    This item arrived exactly as described. While I ordered during the Holiday season (right before thanksgiving), the seller had an automated reply making clear when after the Holiday the orders would be processed. I was pleased to see how communicative the seller was (I didn’t honestly expect a response during the holiday anyway). My order was processed shortly after, and shipped not long after that. My case was ordered for a 40% keyboard (The Van Keyboards “Minivan”), and the fit is perfect. I’m using SA profile keycaps, so while the profile is a little tall for a 40%, it fits just fine in the sleeve. You shouldn’t worry about the case pressing down on your switches. I love this sleeve so much I’m planning to purchase a 60% sleeve soon. Strongly recommended.

    I had wanted to buy two of these for a while but was hesitant at first due to the price but I am extremely glad I went through with the purchase. The materials used are very high quality and are professionally cut and stitched. Everything about these are nice, just buy one if you are thinking about it you will not be disappointed in the slightest. They are so nice that I wish they made more items like laptop bags with this quality. It fits my Core and Nintendo Switch perfectly and I can even throw my iPhone 7 or games in the front pouch so they are versatile in that sense, you don’t need to put a cord in front. The interior material is very soft and wont scratch up anything. I trust it with my switch (lacking a screen protector). The leather tab adds a nice accent too. As I said, just buy one, or two or enough for all your tech

    Just recieved mine and it looks great, and it feels like it is of great quality!
    It will fit most cases for the planck but if the case is larger than normal cases it will be a snug fit 🙂
