The made in Sweden Light My Fire Pack-up-Cup is a portable collapsible cup solution for traveling, camping, and everything in between. The bottom of the cup is made from anti-slip Biobased TPE that collapses into the top section when empty. The upper part is made from Biobased high-density polyethylene (HDPE) that will help keep your drink insulated. It can also double as a measuring cup with marked lines on the inside. These packing cups are BPA-free and are safe to us in the dishwasher. Each cup can hold up to 260 ml (8.7 oz), making it ready for a sip on the go or for a drink in the wild. The lid is designed to keeps beverage hot, avoid spilling and keeps bugs or dirt out.
