Damn I'm really tempted, coz the bust should be seen at eye level not at the bottom of my display - it sits there unoticed, which is a real shame.
Actually im using another cabinet with thicker glass shelves but nearly 3 times longer and has 5 supporting pegs with rubber tips, should be strong enough I think. I might add another glass shelf onto the other - but won't that stress weight on the supporting pegs?
