Brand new, unused. #MolesPC Replacement ball for Elecom ELECOM HUGE Replacement ball, billiard 8-ball This is a third-party replacement ball for the Elecom trackball mouse, HUGE M-HT1URBK, M-HT1URXBK, M-HT1DRBK, M-HT1DRXBK, and M-HT1MRBK. The HUGE body itself is not included in the listing. 【3 times the…】 It's not red. As you can see, it's a black billiard 8-ball. It has a more subdued atmosphere than the somewhat flashy red original, and it's also playful. The same "8" is also printed upside down on the back of the 8. If it looks correct from the front, rolling it back and forth will show the opposite side upright without inverting. 【I like this weight】 Compared to the original's approximately 88g, this one weighs approximately 126g, making it slightly heavier. The original may be better for fine work, but I personally prefer this weight. 【Special Notes】 The original's diameter is 52mm, but this one has a size variation of about 0.1 to 0.2mm. There is no problem with normal use, but if it's larger, removing and installing the ball will be a bit stiff, and if it's smaller, it won't fall out just by turning it over, but if you tap the body from below, the ball will fall out due to its weight. Also, there is a slight step at the boundary between the white and black parts, so it will feel slightly gritty only when the boundary comes to the support ball part. Commercially available 52.5mm balls are quite, or rather, very difficult to install and remove. It's not unusable, but it's a hassle every time you clean it. 【I still love this】 Although there are various flaws, once you replace it with this, you can't go back to the original. I've become attached to it. Rest assured that what you will receive is a brand new, unused item. It will be shipped in a Yu-Packet Plus box.
