The
Luva have many styles, lengths, sizes. All with plastic insert so arm rests comfortably in that and there are no sharp edges to feel regardless of guitar. Feels different--some may or may not like it--but works well. A clever design.
At least it's another possibility.
Made in Brazil. Luva has their own Brazilian website with different prices, but I'm not sure how they are set up to order from currently. In the past, there was some language difficulties and so I purchased from Switzerland. [

The Swiss site worked well.
Shipment was timely.
