A number of Explore Scientific's eyepieces and focal extenders are packed in heavy, oversized boxes. These end up significantly increasing shipping costs, especially for international customers. A few items, such as this one, weigh over 4 lbs when shipped, with the result that we cannot use the cheaper First Class shipping method for international shipments.
Due to requests from several international customers, we are now offering some of these items WITHOUT the original box. The 2" 2x focal extender will be shipped well protected in regular bubble padding. With this, the shipped weight is significantly reduced and you can now opt for First Class shipping during checkout (or slightly cheaper Priority or Express Mail shipping). This item is brand new with full manufacturer's US warranty - you just won't get the original cardboard box if you buy this item.
