We've had quite a few questions and nice comments about the sunglasses, so here are some photos of the manufacturing process. These were really fun to develop, and I took a ton of photos, so apologies if this gets over-long/-enthusiastic! Tender's sunglasses frames are made from cellulose acetate, derived from cotton pulp. This means that as well as being a natural, biodegradable product, they're hypo-allergenic. A lot of cellulose acetate for top-end frames is made from lignin (from wood pulp)
