We’d love for our bottle attachments to fit on every bottle, but unfortunately we have
not mastered this sorcery. Currently the Sprout Collection products fit best on standard PET plastic bottles such as those produced by Coca-Cola Company brands (Sprite, Lift, Coca-Cola, Fanta, Mt Franklin, etc) and PepsiCo brands (Pepsi, Solo, Mountain Dew, etc). They are also compatible with Schweppes bottles or any other bottles with the same screw thread size. Please note that we cannot guarantee all bottles will fit the same due to varying manufacturing tolerances. Some slight deviations should be expected in some circumstances, which could result in minor leakage.

If you are unsure whether yours will be compatible, please send us a message on info@lfornancy.com and we can have a look.

Our products have been carefully engineered to provide a robust seal. We have tested our products on various standard disposable plastic bottles to ensure a good fit. Each item is tested individually for leaks prior to shipping.

If in the odd event you are experiencing unexpected leakage, please try the following:

(1) Check that a standard disposable PET plastic bottle is being used such as those produced by Coca-Cola or PepsiCo brands. (2) Make sure no hot liquids are contained in the bottle as this may warp the plastic. (3) Before attaching the product, check that the bottle screw and product aligns squarely before tightening on the bottle. (4) Avoid leaving the bottle attachment over-tightened on your bottle for several weeks at a time as this could lead to permanent deformation. A ‘2-finger’ grip pressure is sufficient for a good fit. (5) Check that the bottle cap collar is not obstructing the seal of the attachment. If so, carefully remove the plastic collar without damaging the bottle lip. (6) Keep the product away from the hot sun.

If you are still experiencing issues after some of these steps, please send us an email at info@lfornancy.com and we'll try resolve the problem. If you are experiencing some other leakage problems, I'm sorry we can't help you, and please consult a doctor.

Each piece is made from organically sourced polymer that will eventually break down under certain conditions such as temperature, mechanical load and environmental factors.

We recommend the following to prolong the use of your product:

(1) Before attaching the product, check that the bottle screw and product aligns squarely before tightening on the bottle. A gentle (2-finger grip) pressure is sufficient for a good fit. (2) Do not leave your product over-tightened on your bottle for several weeks at a time. (3) Keep away from the hot sun. (4) Do not use with hot liquids, or liquids other than water. (4) Store in a cool dark place when not in use.

If your product happens to break down unexpectedly, please send us an email and we'll try to resolve the issue.

We primarily use Polylactic Acid (PLA), a plant-based polymer that is recyclable and biodegradable under specific conditions. Recyclable Thermoplastic Polyurethane (TPU) is also used for seals. We source high-quality filament to ensure the products are printed with precision and consistency using Fused-Deposition Modeling (FDM) 3D printing technology. We spend more time in the design so that less plastic goes to waste.

PLA is short for Polylactic Acid. It is a plastic derived from organic sources such as corn starch and sugar cane. The monomeric unit of PLA is chemically known as 2-hydroxy-propionic acid, or CH3-CH(OH)-COOH. It is biodegradable under specific conditions and can be recycled. The production of corn-derived PLA has substantially less greenhouse gas emissions compared to petroleum-based plastics of around 30-55%*.

PLA takes on different structural forms based on different temperature ranges. At temperatures above 58 degrees C, PLA becomes rubbery. At temperatures beyond 110 degrees C, PLA starts to become viscous liquid. As warping can occur at hot temperatures, we do not recommend using our products with hot liquid.
