This is a pouch stored at home. It comes with a removable hand strap. You can attach it to the handle of your bag and put your wallet and smartphone in it, which might be helpful to avoid rummaging around in a large bag. The size is approximately 20 x 14 cm, with a gusset of about 2 cm. The strap is about 15 cm from metal fitting to metal fitting. I used to put it in my bag when I went out with my RoBoHoN. The RoBoHoN is a model and is not included. By attaching a long strap to the metal fittings, you can use it as a pochette. I will compact it and send it via Yu-Packet Post Mini. I would appreciate it if you are okay with a used item. The main body will be washed with a cleaning solvent (Hybec) before shipping.
