แกนแข็งสำหรับสอดใส่ Sam STP 3-in-1

I was skeptical about an accessory changing the whole game, but this rod locks in place so securely that I forget it's even there during use. The fact that it converts my existing packer into something penetrative without buying a whole new toy is a huge win, and cleanup was surprisingly quick.

I wasn't expecting that little silicone rod to fit so snugly, but it slides right into the Sam and doesn't budge during use. Massively easier than shelling out for a whole new toy, and cleaning it takes like ten seconds.

The rod slides in snugly with zero wobble once it's seated, which surprised me for such a small add-on. Cleans up in under a minute with soap and water, so it's practical for everyday use. Only gripe is it took me a couple tries to get the alignment right the first time, but now it's second nature.
