What is KOKUYO Gloo liquid glue?

It is a liquid glue built around a square sponge head. KOKUYO says the square shape lets you reach the corners of paper, so the glue is less likely to squeeze out and dirty your hands or the desk. It belongs to the Gloo line with the glue stick and tape glue.

What types and sizes exist?

Strong and wrinkle-free, in different sizes. KOKUYO lists these prices; it does not say whether tax is included.

Item	Size	Price
Strong body	about 50 ml	220 yen (about US$1.39)
Wrinkle-free body	about 30 ml	220 yen (about US$1.39)
Swap-in bottle, either type	same as body	165 yen (about US$1.04)
Body plus two swap-in bottles		550 yen (about US$3.48)
Bulk refill liquid, strong	about 250 ml	660 yen (about US$4.18)
Bulk refill liquid, wrinkle-free	about 250 ml	1,050 yen (about US$6.65)

Prices are Japanese list prices at 158 yen to the dollar. The wrinkle-free glue costs more per milliliter: by our arithmetic 4.2 yen against 2.6 for the strong bulk refill.

How does the bottle swap work?

You replace the bottle and keep the head. KOKUYO calls a refill bottle for heavy users: swapping only the bottle section makes refilling simple. It says the sponge head is durable enough to be reused for five bottle changes, though it gives no test and the head will wear with use.

What does wrinkle-free mean?

An original formula that dries without waves. KOKUYO says the wrinkle-free type finishes without a wave-like undulation and bonds neatly. It does not list the paper weights it was tested on. For another wrinkle-free option, see the Tombow Shiwa Nashi PiT.

Which type should you choose?

Strong for card and everyday gluing, wrinkle-free for thin sheets. KOKUYO’s wrinkle-free body is smaller, 30 ml against 50 ml, for the same 220 yen, so you pay more per milliliter for the formula that avoids waviness. The swap-in bottle is the same price for either type at 165 yen, so the saving from refilling is 55 yen (about US$0.35) a time against buying a new body.

How does it compare with the Tombow liquid glues?

It is a sponge-head glue, while Tombow’s are tip glues. Tombow’s Aqua PiT has a fine tip and a wide silicone tip and a 500 ml refill. Gloo trades the fine tip for a head that covers a whole corner, so it suits flat paper work better than tiny details. Tombow’s refill is cheaper per milliliter, but its body costs the same 220 yen for 50 ml.

Where is it made, and what does it cost?

KOKUYO’s page doesn’t state a country of manufacture. At 220 yen (about US$1.39) the bodies are in our $ band (under $5), and so is the 660-yen strong refill; the 1,050-yen wrinkle-free refill (about US$6.65) is in $$ ($5 to $20).
