The Flosku Aluminium Desktop Stand for Apple Pencil is crafted from solid aluminium with an inner silicone fitting to protect the tip. It comes in silver and black, retailing for £25 plus shipping to Singapore.
The Just Mobile Alupad is a mouse pad crafted from anodised aluminium wrapped in smooth white plastic. The plastic wrap, which sets it apart from the MacPadd, makes the mouse glide more smoothly. I got mine in Bangkok.
I bought the Bluelounge Milo (Aluminium) from Funan's Challenger for S$39, or S$35.10 with member's price. I already own the original Milo from about two years ago, and though the aluminium is S$20 dearer, I love every aspect of it.
MacPadd makes aluminium mouse pads precision-cut from a single block, in two sizes: the 9x6-inch MacPadd at US$25 and the 9x9-inch MacPadd Pro at US$35. Sadly their shop won't ship to Singapore; distributors include MacWay in France and another overseas.
