Floating key chain made of high-density foam, capable of holding approximately 3 keys. - Brand: CHUMS - Model Name: FLOATING NEO KEYCHAIN - Function: Keeps boat keys afloat - Material: High-density foam - Key Capacity: Approximately 3 keys - Color: Fluorescent Green As shown in the second photo, there are fine red lines, which are difficult to see, but present since purchase. I believe this does not affect use, but I would appreciate it if you would only purchase if you are okay with this condition. Thank you for looking.
