Ups , this bag is made of cork !

Properties of cork

• Light: Over 50% of its volume is air, which makes it very light – it weighs just 0.16 grams per cubic centimeter and can float.
• Elastic and compressible: Thanks to flexible cellular membranes cork can be fitted against the wall of a bottle under pressure and when released bounces back to its original form.

• Impermeable to liquids and gases: Suberin and ceroids contained in the cork cell walls makes it practically impermeable to liquids and gases. Its resistance to moisture enables it to age without deteriorating.
• Thermal and acoustic insulator: Due to gaseous components contained in cork it has low conductivity to heat, noise and vibration.
• Fire redundant: It burns without a flame and does not emit toxic gases during combustion. It does not absorb dust and is fire resistant in its natural state.
• Highly abrasion resistant: Cork is extremely resistant to abrasion and has a high friction coefficient. Thanks to its honeycomb structure, its resistance to impact or friction is greater than other hard surfaces.
• Hypoallergenic: Because cork does not absorb dust, it helps protect against allergies and does not pose a risk to asthma sufferers.
