The order was shipped quickly, The delivery to Saint-Petersburg Russia took about 3 weeks, the product was well packaged. The product is as described, the quality is very good.
Filters arrived within three weeks, packed very well, a plastic box wrapped in a foam sheet, another layer of foam sheet inside the box, and each filter sealed in plastic. The quality looks fine, since the filters are narrow band, the require very bright light source with good tolerance to reflected heat. I recommend this seller.
