The teether has a hole, so you can thread a string through it and attach it to a stroller. This applies only to the ice cream teether. I purchased these items from F.O.Online, so I've selected that brand. There are no noticeable scratches or peeling, and they are clean, so you can still use them without any problems. The key toy's batteries are a little weak, so please replace them if necessary. I will disinfect everything with alcohol before shipping, so please rest assured about hygiene. I took the photos on a newly purchased rug, but the rug sheds easily. I've been careful during inspection, but there may be some fibers attached. Please be assured that they are not pet hairs. Please check my profile before purchasing.
