    I love my year of snake knobbys

    I'm really impressed with their comfort level. The fabric is incredibly soft against the skin and the fit is perfect - not too tight, not too loose. The design is stylish and the colors are vibrant will be definitely recommended them to my family and friends

    ⭐️⭐️⭐️⭐️⭐️ Knobby Year of the Snake Edition – Stylish & Super Comfy!

    Absolutely love the Year of the Snake edition from Knobby! The trunks, bikini, and bra are not only well-made but also incredibly comfortable and great-looking. The design is bold and unique, and the fit is perfect. Wore them on my trip, and they felt amazing all day. Plus, the premium Chinese takeaway box packaging was a cool touch!

    Highly recommend Knobby for anyone looking for quality, style, and comfort in their underwear! 🐍🔥

    Long time knobby lover

    My love affair with knobby underwear started almost two years ago now. My mum likes to joke about how fussy I am when it comes to picking and wearing underwear and how this brand is the only one to meet ALL my high expectations. I used to love my bonds, but where my bonds undies wore out within 12 months, knobbies just keep on going. They don't fade, they don't get holes in them, even my oldest pairs still look great. I take care of them by washing them in a wash bag. They're comfortable af, the designs are fun and they make you feel hot. Luckily for me I've gone down a size or 2 and so I have no choice but to continue building my collection in this new size. The best part is I will have knobbies on hand for however my size fluctuates, I can't complain. Keep taking my money knobby. Some people would gawk at spending this amount on a pair of undies, but when they still look vibrant and new after two years of wear and washing, who's really winning? Me, I am.
