Please read the profile description. Pet bottle strap Leather-like Brown Shoulder Cute and stylish♪ Convenient for drinking directly Can be used for up to 600ml If the size fits, it might also work for penlights. I prepared it for use on a trip, but ended up not using it. The clasp will be removed to fit within the regulated size for packaging. For those who understand used items and home storage, recycled simple packaging.
