In 45 years of stamp dealing I have learnt one truism. 
No collector can EVER have too many empty stockbooks! 
Just because you "think" you will not use 10 or 20 (or 30 or 40 or 50) -  you are WRONG!       

Each factory box has 10 x 32 page stockbooks with a combo of covers of Red, Blue, Green and Black.  There are 2 each of 3 colours, and 3 of the other colour to make up the 10.  EACH book is factory cello shrink-wrapped.  This ensures no dust or moisture gets into them before use, (store them until time to use) and also is perfect for gift giving of course.  Lots of stamp clubs buy these for monthly Best Exhibit/Guest speaker type gifts etc.

These are top quality, and famous for many decades, German made "Lighthouse" or "Leuchtturm" brand books.  The BEST!  Surely your stamps DESERVE the best .... and at near HALF the usual storage Hagner Sheet costs - why ever not?!  The photos above were taken by me, and are of the exact books and colours you actually receive.  Attractive grained leather look covers and spine as you can see, with the classy Gold Lighthouse logo and Gold spine banding.

Do NOT even think of buying Asian made and/ or "No Name" stockbooks.  They all look cheap and nasty right from day #1, all pages and covers are generally highly acidic, mostly are non-linen hinged, and the pages readily warp.  They can RUIN your stamps, as the highly acidic board and glassine content, combined with our humidity, bathes your stamps in literally a weak acid bath - all year long.  Decade after decade.  This accelerates toning/foxing, which RUINS your stamps.  "Saving" a few dollars a book could ruin your stamps worth many $1,000s.  Just dumb.  

Lighthouse uses neutral bleached board for pages and covers to alleviate this problem.  German top quality.  For many decades the brand "Lighthouse - Leuchtturm" in stockbooks and stamp accessories has been synonymous WORLDWIDE with meaning "top quality".  The BMW or Mercedes Benz of the stamp storage industry.  All with the famous 5 Gold embossed bands on the spines, and the famous "Lighthouse" logo in Gold on spine and front cover.

The black page books have CRYSTAL CLEAR strips - 9 strips per page.  This is much more expensive than the glassine used on white page books to manufacture of course, but with waxed paper glassine strips, your stamps are always half hidden behind murky/cloudy type glassine when you look at them.  Look at the photos nearby - can you even see where the strips ARE??  You see 100% of the stamps.  VERY few stockbooks (only a few %) sold in the past 25 years have CLEAR strips, as the cost to make them is high. 

Strong LINEN HINGED pages on both sides for very long wear, and DOUBLE glassine interleaving to protect all your stamps - and stopping the cheaper single interleaved pages from tangling and crumpling up - which they ALWAYS do!  For a while Lighthouse experimented with clear plastic interleaving pages.  These were a disaster, as static electricity charges build up from synthetic carpets and clothing, and the 2 interleave pages "stick" to each other, and crease easily, and stay creased, and look terrible very quickly. 

HINT AS A GIFT!!  Tired of Gifts that you do not really want - well hint to the Spouse or kids that a box of LIGHTHOUSE STOCKBOOKS is the smartest thing they can buy you.  Print out this page, and leave around the kitchen a week before Birthdays, Christmas or Father's Day or Mother's Day etc!  

Postage and insurance is of course extra on all orders, but as always, I use carefully selected, light cancelled, philatelically VERY valuable stamps and se-tenant strips, small run modern mini sheets of 10 etc, on every carton mailed.  So the "real" shipping cost is often basically zero to you.  POSTAGE ON TWO BOXES is near exactly the SAME as ONE box within Sydney region area!  (+$5 for Registered on all Australia orders.)  Shipping interstate or overseas is much higher of course, but superb CTO franking under protective plastic is used - often worth more used than you pay for shipping - see here for endless proof - http://tinyurl.com/GlenShip   So you save a LOT on shipping if buying your stockbooks in one order.  Band together with a few folks at the local stamp club - SMART.  Many do.

At under $A1 a page, getting 2 cartons is a deal you cannot NOT seriously consider.  Near HALF the page price of a Hagner sheet!   In nearly all of Australia, heavy parcels are delivered to your door by an Australia Post Parcels Contractor - i.e. no lifting for you!  All boxes are sent Registered Post (+$5) for signed-for security in Australia.  Full "all risk" Marine Transit Insurance is wise, due to wet weather or theft or damage issues - cost is only $2 per $100 covered, or just $7 extra per box 10, and is added to invoice unless you decline it in writing on order form, in which case you assume total risk.  

Boxes of these at times have arrived damp at base, due to wet weather somewhere on route, or in mail vans etc, with all books wet and buckling. Just $7 extra a box of 10 covers full replacement cost insurance, if your PO records the damage on arrival.  Insured mail for anything worth above $100 is getting to be ESSENTIAL these days sadly - as I outlined here recently - www.tinyurl.com/APtrack

And remember if you buy the box of 20, your books are wonderfully extra protected from transit corner damage, being DOUBLE boxed.  Each box of 10 is in a separate Factory Carton.  Then both those cartons are in a REALLY thick purpose made outer cartons - as they were shipped from Germany in, on pallets.  Even if dropped from a metre up, a box of 20 will survive!  

That is 320 pages of top quality low acid, black page storage for under $A1 a page in bulk buy.  A British made HAGNER sheet is RRP $A1.75 each these days - with no binder of course!  So you are getting classy German made 'Lighthouse' stockbooks for in effect near HALF the price per page of 32 Hagner sheets - which have no binder or cover!  (And which of course are nowhere near as classy or permanent a storage medium, as a Lighthouse Stockbook of course!)

Order fast before these are sold out - last shipment was gone in WEEKS.  My next shipment will likely cost me FAR more with the strong Euro/weak AUD - sad but true, as wholesale price has also increased - I cut my own margins to keep prices the same on this shipment.  Band together with a friend and share them 5 each, or order a carton or two via your stamp club etc. 

One client in Newcastle has ordered THIRTY cartons (300!) of these off me since I have ran this special.  He has a bookshelf stacked with them he advises!   As I point out above, the postage cost to him for TWO cartons (20) is the near the same in $$s as ONE carton!   A huge carton delivered Registered Post right to your front door for $25 seems nuts.  Just ONE stockbook attracts the near identical mailing cost - literally.   A strange Australia Post quirk.

REMEMBER:  It is a great idea to now and again re-house ALL your stamps.  At this price why not do that NOW?  Stockbooks 15-20 years old WILL have mould growing on the pages if stored in Australia.  NO doubt about it.   In any eastern coastal areas it will start in under 10 years.  And on black pages it is VERY hard - indeed almost impossible -  to see with the naked eye.  You WILL see it using a cheap UV lamp - go check your books!   For just over $A30, a new stockbook to put your $1,000s of stamps into makes superb sense.  Foxing/rust on them might lose you $1,000 - or far more of course.
