Made from biodegradable PLA (Polylactic Acid) Plastic - a type of thermoplastic polymer derived from renewables like corn starch and sugar cane. It's 100% biodegradable, recyclable, and compostable- and is free of contaminants.
In terms of strength, it's very solid - PLA has one of the highest tensile strengths in 3d printing. It's also very lightweight, helping to minimize fall damage.
