Total length is not usable depth
The tool is approximately 46 × 253 × 40 mm. Its overall length includes the handle and does not directly state the depth it can clean inside every bottle. Measure the mouth and internal shape as well.
A narrow opening, shoulder or internal step may restrict movement even when the tool enters. Imagine the full cleaning motion rather than checking only whether the head can pass through the mouth.
Check the coating and separate parts
The manufacturer excludes fluoropolymer-coated and lacquered surfaces and chlorine bleach. Read the bottle maker instructions too. The published acrylic and cotton cover materials do not establish compatibility with every coating.
Bottle bodies, lids and seals need different access. This tool should not be assumed capable of cleaning every lid channel or gasket. Follow the bottle instructions for disassembly and cleaning instead of forcing the tool into small parts.
Inspect before using again
Check the handle, cover and attachment before use, and allow the tool to dry after rinsing. A visibly damaged part is a reason to stop and consult the manufacturer instructions. Avoid excessive rubbing.
The configured offer is the green K472G single item. Verify the variant and quantity at the seller. This is an analysis of official information; it does not report a hands-on durability test or claim a measured cleaning score.
