The 5 caps could be sent in the normal letter without problems. The package was announced by DHL, but did not come without a cancellation. The following day it was taken away again without inserting a card. My wife then had to go there twice and, despite the power of attorney, only got the package because a DHL colleague at the neighboring counter assumed responsibility. I was on a business trip in Bulgaria and the package would otherwise have been returned to SVB. All in all not acceptable from my point of view.
These so-called flat head caps for lens heads or lens-like heads are usually sold in 100 steps. (same dimensions as this one). With a normal minimum order quantity of 1000 pieces, they normally cost € 0.98 per 100 pieces and not this price for 1 cap. This is real usury and means a surcharge of 10000% (unit price at a price of € 1000.98 € 0.0098 per piece. You do the calculations yourself. I've been sailing for 40 years but I've never seen anything like that really great !!
