This adapter was specifically made for Casio Tactical Mudmaster GGB100 series.
It's one size that fits all. The strap inside the photo was 22mm. The maximum width supported by this adapter is 24mm. I would highly recommend 22mm - 24mm strap to be used with this adapter.
You can safely remove the factory resin band by following Youtube video. It take about 5 minutes to do so. You will need a Hex wench tool which is very common tool everywhere. Please check this video: https://www.youtube.com/watch?v=ry-g5zzXiZc&t=987s
Currently available in Resin Black and Resin Transparent. It's printed with Engineering grade tough resin. VERY LIGHT YET TOUGH AND DURABLE. I will explore more Pattern and different color of resin mix in the future.
