Unopened box! This device helps put on compression socks as well as take them off. Only one of these devices is necessary to have for many years. Other aids of this sort retail at $100+ I wasn't sure what this was EXACTLY, but I found very helpful videos on the Midi website. German product. Here is more info on the product from their website: "Mediven 2 in 1 donning and doffing aid is a first-class, completely newly developed product that is specifically tailored to the requirements of all compression stocking wearers. It supports you in getting the compression stocking over the instep and heel when putting it on. This also applies to the opposite direction, as it also serves as a removal aid for compression stockings and minimizes the effort required to a comfortable minimum. The mediven 2 in 1 putting on and taking off aid can be used for any length of stocking (knee, thigh stocking or tights). This does not change handling."
