You cannot purchase it anywhere, currently
It is out of stock everywhere I would recommend looking.
It is the Adonit Pixel.
https://www.adonit.net/jot/pixel/
It is compatible with iPads all the way back to the 2012 iPad 4th generation and iPad Mini.
You will not find this, ANYWHERE currently!
I recommend this stylus A LOT here and I check for availability often
If you are using a drawing or writing app with a NON-Bluetooth stylus, then a drawing glove is essential.
They are less than $10 U.S.D. and can be easily found on Amazon.
The drawing glove has another benefit. I allows your hand to move more easily across the iPad's screen.
Do you want to try cheaper Non-Bluetooth stylii you can get now to use with all drawing/writing apps?
I’ll give my own recommendations, anyways.
I recommend a common capacitive stylus with a clear disc tip for better accuracy as you can see exactly where you ate going to mark through the disc.
The best one of these I can recommend is the Adonit Pro 4 as it has a disc that is more durable, glides easily and is resistant to scratching the iPad's screen. You still need to keep the disc free of dirt and dust particles and keep your iPad's screen clean, before using.
Another type of NON-Bluetooth stylii is the so-called fine point, “active”, battery powered capacitive stylus that the battery generates a tiny electrical signal to the fine point tip of these stylus that simulates a finger touch.
There are many of these on Amazon, but all of them are NOT created equal.
This type of stylus tends to create some some line wobble, especially with angled lines, but some of these have better placement accuracy and have less line drawing wobble than others.
Again, the best of these I can recommend is, once again, from Adonit.
It is the Adonit Dash 3.
https://www.adonit.net/dash/
This is a well made “active”, rechargeable, Lithium-ion battery, fine tip stylus.
Works without any Bluetooth connection and its angular line wobble is less pronounced and will be minimised more by drawing with the stylus at a faster, not slow velocity onscreen.
Has a single ON/OFF button and charging port at the top of the stylus.
Capacitive stylii work with any iPad screen and any iPad app.
Here is just one example of a special, lycra material based, non-body electrical conducting drawing/writing glove.
Something like this found on Amazon.

Many more makers of these types of gloves found on Amazon and in different hand sizes, and colors as well!
Best of Luck to You!
