Thanks so much for your feedback, we really appreciate hearing what our customers think of our products and service. Regarding the size of the necklace, we try hard to convey the size of the disc by including the dimensions of each disc on our website, and including a model shot so that our customers can see what the jewellery looks like when worn. Please do let us know if there are any ways in which you think we could make this clearer. Regarding having to pick your parcel up from the Post Office, we send our more expensive pieces by Recorded Delivery, to help ensure they reach the customer safely and in good time. If you order with us again, and would like your parcel to be sent by Standard First Class instead, we would be more than happy to do this - simply let us know in the "Order Notes" section and we'll make sure the order isn't sent by Recorded Delivery. Thanks again for your detailed feedback.
