Incense resin, derived from the sap of trees and plants, is known for its long-lasting aromatic qualities. Unlike many organic materials, resin does not "go bad" in the traditional sense. Over time, it may lose some of its potency or fragrance intensity but does not spoil or become harmful. Proper storage, away from direct sunlight and in airtight containers, can significantly extend its usability. However, if resin gets contaminated with moisture, it might develop mold or lose its burning properties, making it less effective. If stored correctly, incense resin can retain its aromatic properties for years, making it a durable choice for those seeking natural fragrances for their living spaces.

Polyvinyl Chloride (PVC) pipes are commonly used in DIY hamster cages for tunnels due to their durability and ease of cleaning. However, safety concerns arise due to the potential risk of ingestion. While PVC itself is not toxic to hamsters if ingested in small quantities, the plastic can cause internal blockages or injuries. Moreover, chemicals like phthalates, used to soften PVC, can be harmful if leached into the animal's environment. Therefore, it's crucial to ensure that any PVC component used in your hamster's habitat is free from toxic substances and is too large for them to chew on. Regular inspection for bite marks and damage is advised to prevent any accidental ingestion. Alternatives like cardboard tubes, which are safer if ingested, can also be considered.
