A vessel for your odour that is hidden in a bolt! Yes, yes it's the old bolt trick but why not?
Made of PLA filament
PLA has an excellent resistance to oils and greases and to many other chemical agents; it offers a good barrier to aroma and oxygen, a low barrier to steam.
Main characteristic of the PLA is a 100% biodegradability and a 100% compostability.
Use caution if rewarding your dog with food to avoid accidental consumption.
