When we switch to PETG

Anything that gets warm, wet or knocked about: coffee-corner accessories, bathroom caddies, plant pot trays and picnic gear. Our strength and heat guide explains the trade-offs.

Care

Hand wash in warm soapy water. Not recommended for long-term outdoor UV exposure; choose ASA for that.
