Climbing Bouldering Botte Volume Holds DIY

Handmade wooden climbing holds.
Made by combining 30mm and 12mm plywood and scrap wood.
The gray holds were coated twice with water-based paint mixed with cement for friction.
The triangular holds were friction-finished with water-based paint and #6 silica sand, and the small red holds were friction-finished with oil-based paint and #6 silica sand.
Countersunk holes with embedded washers are provided for wall mounting.
This is my first creation, and there are still some rough edges, so I am offering it at a low price. However, I aimed to create high-quality holds with good durability, so I believe they can be used without any problems.
How about for your private wall?
