Knife Aid

Knife Sharpening by Mail - fast, convenient and professional. An on-line business model of an old trade. Our mission was to develop a sustainable business that does not contribute to more consumption, but instead maintains and restores the value of what we already own, while at the same time bringing joy to the preparation of what we like the most -- food -- and a life in the outdoors.

Bug Bite Thing

Bug Bite Thing is a SUCTION TOOL that extracts insect saliva/venom from under the skin to help alleviate the itching, stinging and swelling that occurs with bug bites and stings. When you remove the irritant, your body stops producing the reaction that is causing the uncomfortable symptoms. Bug Bite Thing is kid friendly, reusable, and works great for mosquitoes, bees, wasps, ants & other biting insects.

Plop Star

Plop Star is the world's most discreet and portable toilet odor eliminator. Each Plop Star tablet is individually wrapped for portability and fits in a wallet, pant pocket, jacket or small purse. Drop one tablet in the toilet bowl BEFORE your performance. Plop Star tablets start dissolving instantly, releasing a buffer of essential oils on the surface of the water that trap bathroom odors before they start. Plop Star leaves a subtle citrus scent behind, and nothing else. So you can rock the bowl with confidence, anywhere, anytime.


SNACKLINS started as a joke between friends to create a vegan pork rind, but that joke has gotten way out of hand. SNACKLINS is a delicious, guilt-free crunch made from real, fresh ingredients you can pronounce: yuca, mushrooms, and onions. Not to mention, SNACKLINS are only 80 calories for the whole bag. SNACKLINS is on a mission to make your snack time a little more flavorful and those flavorful moments absolutely guilt-free.
