Common questions
What's the difference between flexible and brittle sealing wax?
Flexible wax (also called 'glue gun wax') bends without cracking when it cools, so it survives postal sorting machines. Traditional brittle wax is harder, takes richer colors, and has a more authentic drip aesthetic, but will crack if mailed. Use flexible wax for anything going through the post; brittle wax is fine for decorative, non-mailed seals.
Can I use a regular glue gun for wax seals?
Only if it's a low-temp model. Standard high-temp glue guns run too hot for sealing wax and will scorch it. Low-temp glue guns (typically marked for crafts, not construction) are designed for exactly this use. Confirm your gun has a 'low' setting before buying wax sticks designed for it.
How do I stop my wax seal from sticking to the stamp?
Let the wax cool for 15–20 seconds before pressing (it should look matte on top, not shiny). Lift straight up, not at an angle. If it still sticks: your wax is too warm. Brass stamps release better than zinc, worth the few extra dollars for a brass head if you're getting consistent sticking.
Will wax seals survive mailing?
Flexible wax seals (not brittle traditional wax) survive first-class mail about 90% of the time if you hand them to a post office clerk rather than dropping them in a collection box. The sorting machines that eat seals are mostly in bulk-mail facilities. For important correspondence, put the sealed envelope inside a plain outer envelope to be safe.
How do I get clean, crisp impressions?
Three variables: wax volume (too little = incomplete design fill; too much = overflow), wax temperature (test on silicone mat first), and press pressure (firm, straight down, held for 10 seconds). The most common beginner problem is lifting the stamp too early while the wax is still liquid around the edges.
What's a good starter stamp design?
Bold, simple designs with clean lines: a single initial, a classic botanical motif (leaves, branches), a simple geometric, or a sun/moon shape. Avoid fine script, tiny dots, or anything with intricate thin lines until you have consistent temperature control. Simple designs produce impressive seals your first day; complex designs require weeks of practice.
